Suddenly a flashback came into Sooyeon's mind.

Flashback ;

"Oppa, whats this book about?" asked little Sooyeon curiously

"Oh, come let oppa see" said Jaejong as he placed Sooyeon on his lap and took the book from Sooyeon.
"Oh, its a book that teaches how to heal people, Sooyeon"

"Then what about this?" asked Sooyeon as she pointed to a page that shows a picture of somewhat a royalty in it but she doesnt know how to read it.

"This?"
"Its teaching you how to heal someone who's immortal during emergencies"
"And this page says, all royalties blood are able to cure almost any injuries" explained Jaejong

"So does it mean our blood can save everyone, oppa?" asked Sooyeon sweetly

"Yup we can"
"But the sad thing is, we cant save ourselves with our own blood"
"So dont try to get hurt really badly in future okay Sooyeon?" smiled Jaejong as he ruffled his cute sister's hair

"Araesso, oppa" smiled Sooyeon as she continued flipping through the books around Jaejong's study desk.

Sooyeon's POV

Yes, thats it.
The royalties' blood.
My blood can save Donghae.

End of Sooyeon's POV

So Sooyeon quickly grabbed a knife and slashed her wrist, letting her blood drip into Donghae's mouth.
But she didnt know how much was required to save him, so she let her blood drip into Donghae's mouth till Donghae regained consciousness.
Donghae slowly opened his eyes, but was shocked to see Sooyeon beside him with her wrist on top of his mouth with all the blood on it.

"Jessica?!"
"What are you doing?!" exclaimed Donghae as he held onto Sooyeon's wrist.

Sooyeon was already struggling to keep herself conscious.
But she had already exerted too much strength,power&blood.

"Im saving you"
"What do you think i was doing?" snapped Sooyeon irritated as she took her wrist away from Donghae and went over to Soojung's beside and look at her,
making sure Soojung's doing well.

"Jessica.." started Donghae

"Stop, im really very exhausted now"
"Dont, dont ask me or tell me anything"
"You just lay back down and rest, you've gone through a lot today" instructed Sooyeon as she laid her head on Soojung's bed while holding her hands.

"But Jessica..?" called Donghae again but received no reply from her, probably guessing that she was already asleep.

At that point of time, millions of questions were entering Donghae's mind.
Expecting that Donghae will for sure shoot her with a lot of questions, she just told Donghae to rest and leave everything for later.
She doesnt want to answer anything for the timebeing because firstly, she was worried for Soojung.
Secondly, she was really really exhausted. Thirdly, she wanted Donghae to rest first as Donghae was hurt pretty badly.

The next morning, when Soojung regained conscious,
the first person she saw was Sooyeon, holding onto her hands.

"Sooyeon unnie!!!" exclaimed Soojung on the verge of tears.
"Sooyeon unnie!! Soojung missed you so much!!" cried Soojung as she hugged Sooyeon
"Sooyeon unnie?!"
"Why are you so hot?!" cried Soojung as she started shaking Sooyeon, hoping to wake her up.

While on the other hand, Donghae who was lying on the opposite bed woke up too.
Only to see Soojung crying&shaking Sooyeon hard but there was no response from Sooyeon.

"Whats wrong Princess Soojung?" asked Donghae as he stood up and walked over to her.

"Sooyeon unnie"
"She's not waking up Donghae oppa"
"She's boiling!" exclaimed Soojung with worry

"Must be because of Amber last night"
"She's hurt badly too" explained Donghae

"Sooyeon unnie took a blow for me from Amber!" sobbed Soojung
"Donghae oppa, what do we do now?!"

"We're reaching the land soon"
"I'll bring her to the hospital as soon as we get down"
"For the time being, put her on the bed first" instructed Donghae calmly

But deep down inside Donghae's heart, he was really worried.
He didnt want anything to happen to Sooyeon.

"So she is Princess Sooyeon?" asked Donghae
"The princess i've been asked to search for the whole 8 years?!"

"Yes Donghae oppa"
"She's the one" replied Soojung as she slowly laid Sooyeon onto the bed.

"How could this be?!" exasperated Donghae
"How could something like this happen?!"
"How could i fall in love with a royalty?!"

"What?!"
"Donghae oppa?!"
"You're in love with my unnie?!" exclaimed Soojung shocked

"Yeah.." said Donghae sadly

"Nevermind about this Donghae oppa"
"As long as unnie is fine with you"
"We wont do anything" said Soojung
"But should we bring unnie back?.." asked Soojung worriedly

But just as Donghae was about to reply, Sooyeon woke up and tugged Soojung's wrist.

"Sooyeon unnie?!"
"Kwenchaena?!"

"Dont.. Soojung.."
"I dont.. wanna go back.." said Sooyeon weakly with tears falling down

"Why unnie?!"
"You're health is in danger now!"

"No.." said Sooyeon as she started standing up, trying to walk away from them but failed as she fell onto the floor.

"Princess Sooyeon"
"You shouldnt do this.." said Donghae disapprovingly

"Princess Sooyeon?!.."
"I dont even deserve that name.." mocked Sooyeon weakly

"Sooyeon unnie, appa&omma had found out who was behind the whole incident 8 years ago"
"They've forgiven you, and have been searching for you since then"
"Jaejong oppa is already waiting for your return unnie" explained Soojung

"Whats.. the point..?"
"Soojung.. i dont want to return.. anymore.."
"I dont know.. how to face.. them.." said Sooyeon

"And you, Donghae.."
"Why didnt you tell me.. you were.. a knight..?"
"Why..? You shouldnt.. even have.. taken.. Amber's fight.."

"Its my duty to protect Princess Soojung"
"Even if its to the end of my life"

"What if your life.. really ended last.. night..?"
"Did you.. even spare a.. thought about me..?"
"I thought.. you said you.. love me.." challenged Sooyeon weakly as rubbed her chest in pain

"I love you"
"But you're a royalty.." started Donghae

"So what if.. i am one..?"
"Does that.. gonna stop.. you from.. loving me..?"
"If yes.. i think.. i've done the.. wrong thing last.. night.."
"For saving you.."

"Sooyeon unnie!"
"You saved Donghae oppa last night?!"
"But how?!"
"There's nothing here!"

"My blood.."
"The blood of a royalty.."
"Can cure all injuries.."
"Jaejong oppa.. once told me.."

"You gave Donghae oppa your blood?!"
"How can you do that?!"
"You know thats gonna harm you body even more!" exclaimed Soojung angrily

"Yeah, you shouldnt have done that"
"My life's not as precious as yours.." said Donghae sadly

"Shut up..Donghae.."
"Its my blood, its up to me.. to decide.. how worthy.. you are.."
"Soojung.. Let me take a rest first.."
"Wake me.. up when we.. reaches the land.."
"Dont ever.. dare bring me..  back.. or tell oppa..anything.." warned Sooyeon as she drifted back to sleep.

"Donghae oppa"
"What should we do with Sooyeon unnie..?"
"Only if she goes back to the heaven then can she recover fully.."

"Should i go and look for Prince Jaejong for help?" suggested Donghae

"NO!!"
"Didnt you heard what unnie says?"
"She dont want Jaejong oppa or anyone else to know" said Soojung

"Fine fine"
"Then as soon as we reaches China, i'll get the earliest flight for us back to Korea"
"Korea's medical help is better than China, im sure we can get back on time" said Donghae as he started fiddling with his ipad, trying to secure the earliest flight back to Korea.
"All done, its an hour right after we alight from this cruise"
"So we have to hurry Princess Soojung"
"Lets pack our stuff"
"We're reaching soon" concluded Donghae as he looked through the window that were in Sooyeon's bunk.

"Okay Donghae oppa" replied Soojung as she quickly ran to her room and grabbed her stuff.

An hour later, Donghae,Soojung&Sooyeon was on the plane, ready for takeoff.
It will take them 1hour&30minutes before they could reach Incheon Airport.
On the plane, Soojung was holding onto Sooyeon's hand throughout the whole journey without letting go at all.
She was really worried for Sooyeon, and she missed Sooyeon's touch too.
Not by a little, but a lot till the extend that its beyond description.

"Sooyeon unnie?"
"Are you still feeling very uncomfortable?"
"We're reaching soon" said Soojung as she saw Sooyeon frowning with beads of cold sweat dripping down her forehead.

"Jessica?" called out Donghae caringly as he felt for Sooyeon's forehead.
"You're really burning up, whats wrong?"
"Please, dont let anything happen to you" said Donghae worriedly looking at Sooyeon's pained expression

Finally, their plane landed and Donghae piggybacked Sooyeon out while Soojung went to settle their luggages.
Soojung went to get the delivery service for their luggages back to their house since they are in a hurry to bring Sooyeon to the hospital.

"Princess Soojung"
"Are you done?" asked Donghae as he saw Soojung walking towards them

"All done"
"Quick, get unnie to the hospital now Donghae oppa"

"Okay, lets go and get a cab"

In the hospital

"How is she doctor?" asked Donghae worriedly

"She caught an infection, leading to the high fever"
"And her blood level is like pretty low"
"Is she anaemic?"

"No, unnie's very healthy" interrupted Soojung

"Okay, well"
"Back to her infection, i realised she had a pretty deep cut on her back shoulder"
"It looked like it have been stitched up before but it opened up again"
"And thats why it got infected, you guys should have taken better care at such a deep cut"
"Admit her into the hospital for further tests if possible"
"If not, bring her home only when she finishes 2 bags of IV" instructed the doctor before he left

"Kamshahamid doctor"
"Sorry for the trouble!" said Donghae as he bowed politely to the doctor.

Then, Soojung&Donghae walked into Sooyeon's temporary ward that was located at the A&E department.

"Jessica.."
"The doctor says you have to be admitted into the hospital for further tests.."
"If not, you can only go home after 2 bags of IV" explained Donghae softly

"I.. dont want.. to stay here.."
"Just bring me.. home.."
"I wanna.. go home.." replied Sooyeon softly with teary eyes

"Okay Sooyeon unnie"
"We'll bring you home, but please finish this whatever it is called" said Soojung as she pointed to the IV.

It was actually new to Soojung since she was new to Earth.
She didnt know there's actually something like that used to treat patients on Earth.
Back then, in heaven, they dont used things like that but only simple stuff like jabs&medicine only.
Because normally those in heaven dont fall sick so easily&seriously.

"Thanks.. Soojung.." replied Sooyeon before she drifted back to sleep.

"Do you really think we shouldnt report it to the King/Prince?" asked Donghae worriedly

"No, not at the moment"
"Wait till unnie's all well again"
"I dont want to agitate her incase she runs off like 8 years ago"
"I dont want to be separated with her" explained Soojung sadly while she recalled what happened 8 years ago.

8 years ago, Sooyeon left Soojung&her family without saying a single word.
All she did was she left a letter¬hing else.
8 years later, which is now, Soojung found Sooyeon but at the wrong timing.
But if Amber didnt appear, till now Sooyeon would still be hiding from Soojun,
and they couldnt have met.
Sooyeon couldnt have know that Donghae's a Knight instead of a normal human being.

6 hours later, after Sooyeon had finished her treatment in the hospital,
Donghae then piggybacked Sooyeon back to her own house together with Soojung.

"Wow, unnie"
"This is where you've been living for 8 years?"
"Its in such a remote area"
"No wonder Donghae oppa cant find you" said Soojung as they walked into the house

"I found her, its just i didnt know it was really her"
"I mean her being the lost princess" explained Donghae as she slowly lay Sooyeon onto her bed.

"Rest well okay Jess?" smiled Donghae as he pecked Sooyeon's forehead before leaving her room to the kitchen to cook something for Sooyeon to eat when she wakes up.

Few days later after the whole incident, Sooyeon had basically recovered from everything.
There's something thats actually troubling her after the whole incident.

Sooyeon's POV

Why is it that my chest hurts at times?..
And im getting out of breath easily..
Whats going on..

End of Sooyeon's POV

"Sooyeon unnie!" shouted Soojung as she skipped into Sooyeon's room happily

"Yup Soojung?"

"Sooyeon unnie, why didnt you go back to heaven and look for Soojung?" pouted Soojung
"I missed you.."
"And why dont you allow me to tell Jaejong oppa&appa about you?" asked Soojung innocently

".."
".."
".."

"Sooyeon unnie?"

"Soojung, dont force me okay?"
"I just dont feel like seeing them yet.."
"Im always being reminded of the past.." mumbled Sooyeon

"Okay.."
"Sorry" said Soojung sadly

Just then, Donghae entered the room with a smile on his face.
That smile of his were no longer like the ones he had when he was a playboy.
It really seemed that Donghae has changed for Sooyeon and Sooyeon's starting to experience Donghae's love for her bit by bit.
Their love is simple but simple is beauty.
Sooyeon slowly started to accept Donghae through Donghae's sweetness.
Donghae's been extremely sweet&considerate to Sooyeon especially after Amber's incident.

"Hi babe"
"How're you feeling today?"
"Better?" asked Donghae caringly as he sat down on Sooyeon's bed

"Yeah" replied Sooyeon
"I wanna return back to school tomorrow" announced Sooyeon

"Wae?!"
"Sooyeon unnie! you're not well enough to be back in school!" exclaimed Soojung

"Yeah, why not  you stay home a few more days?" suggested Donghae

"No, i wanna go back already"
"Im already rotting on my bed" said Sooyeon as she glared at Donghae

"Okayokay"
"I get it, dont glare at me like that" surrendered Donghae

"Good" said Sooyeon as she turned to Soojung.
"Soojung-ah, go back to heaven okay?"
"Its too dangerous for you to be here"
"Look at what Amber did" said Sooyeon slowly
"Unnie doesnt want anything to happen to you"
"You understand me?" asked Sooyeon as she cupped her hands onto Soojung's face

"Why unnie?"
"Im going to miss you" teared Soojung sadly
"I dont want to leave you"

"You cant, Soojung"
"You're too dangerous here"
"Amber will come back anytime soon" explained Sooyeon

".."
"What about you unnie?"

"Im good enough to finish Amber off" smiled Sooyeon assuringly
"So dont worry okay?" said Sooyeon as she patted Soojung's head
"Donghae, please send Soojung back"

"Okay, i will" promised Donghae

"Send her back safely, now"

"Now unnie?!"
"Isnt it too fast?!"
"Cant i stay here a little bit longer?!" exclaimed Soojung in shock.

"No Soojung"
"I dont want you to get into any dangerous situation anymore" said Sooyeon sadly
"And, when you get back home"
"Never tell anyone about Amber or meeting me okay?"

"Okay unnie"
"But please come back soon"
"We miss you" sobbed Soojung softly

"Okay, i will"
"Now go on" smiled Sooyeon
"Donghae, go, bring her back now" said Sooyeon as she pushed Donghae&Soojung together.

"Okay, we'll be going now Jess"
"I'll be back soon" winked Donghae as he left the house with Soojung.

"Finally, they are gone"
"Hmm.. i wonder if Amber will be back for revenge.." whispered Sooyeon to herself but stopped when a sudden urge of pain came into her chest but went off minutes later.
"Seriously, what is wrong with me?.." grumbled Sooyeon as she rubbed her chest to ease the pain
"Think i should practice my elements now, incase Amber attacks again"

In the Great Hall

"Oppa, appa!"
"Im back!" shouted Soojung excitedly as she entered the great hall with Donghae

"My respects to your majesty&your highness" greeted Donghae as he steps into the great hall

"Oh, my baby jung!"
"How was Earth?" asked Jaejong happily

"Earth was great oppa!"
"I met a lot of new friends!"
"But i decided to come back up again!" giggled Soojung

"Soojung, did you managed to find your unnie?" asked the King eagerly

"Er.."
"No appa" lied Soojung as she averted the King's gaze

"Oh really..?"
"Oh well.." replied the King sadly as he turned to walk away.

"Yah Soojung"
"You lied to appa right..?" questioned Jaejong suspicously

"Ani oppa!" said Soojung

"Dont lie, i know when do you lie!"
"Donghae, did you find Sooyeon?"

"I.. er..." stuttered Donghae

"I see.. everyone is keeping something from me"
"Hmm.."
"Soojung, oppa will let you do the honour by telling me the truth"

".."
".."
".."
"Okay oppa, if i tell you, dont tell anyone else okay?"
"Especially appa&omma" winked Soojung

"Okay"

"Promise?" asked Soojung as she sticked her hand out for a pinky promise

"Promise" smiled Jaejong as he finished the pinky promise

"Princess Soojung.."
"You sure..?" asked Donghae worriedly

"I think so"
"I think oppa deserves to know"
"Oppa, we found unnie" giggled Soojung happily

"What?!"
"You found her?!" exclaimed Jaejong but was quickly stopped by Soojung

"Shh.."
"Oppa! How can you be so loud?!"
"Yeah, we found her we i went on a school trip with the school"
"And Amber was there too.."

"Amber?! You mean the only descendent of the underworld?" questioned Jaejong

"Yup"

"Then are you alright?!" asked Jaejong worriedly as he spinned Soojung around checking for any injuries

"Kwenchaena oppa"
"Sooyeon unnie saved me"
"She save Donghae oppa too"
"And got hurt too.. " said Soojung sadly

"Yes, Princess Sooyeon saved me with her blood when i was on the brink of death after getting hit by Amber"
"And yes, Princess Sooyeon got hurt because she shielded a huge blow from Soojung.." explained Donghae

"WHAT?!"
"How could all these happen?!!"
"How is she now?!"
"You all should have brought Sooyeon back here.."
"There's a better treatment for her here.."
"And Amber's strength is no kidding!"
"It could have harmed Sooyeon's internal organs.." said Jaejong worriedly

"It could get so serious oppa?!"
"I didnt know that"
"Omo!" exclaimed Soojung in shock
"But Sooyeon unnie doesnt want to come back oppa"
"She seem to like, kinda scared of coming back" said Soojung

"Why?"
"Is it because of the incident 8 years ago?"
"Its over already.."

"I know, i told her"
"But i think the incident 8 years ago left a huge scar in her heart"

"I think so too, Prince Jaejong"
"When i first met her, her heart was totally shut, cold&broken"
"No one could get close to her.." explained Donghae

"Till now, Sooyeon unnie got better after being with Donghae oppa"
"A little better" grinned Soojung
"Donghae oppa's love for Sooyeon unnie slowly slowly opened Sooyeon unnie up, oppa!"

"Really Donghae?"
"You love my sister?" asked Jaejong suspiciously

"Yeah, i guess i do" admitted Donghae shyly

"Okay, im not going to stop you"
"But if my sister gets hurt because of you"
"You're screwed"
"You understand me?" warned Jaejong sternly
