The pain is so bad that Yerin is taken to a nearby hospital where she diagnosed with appendicitis. Doctors informed her that, as of right now, her inflamed appendix does not need to be surgically removed. Instead, they hope that, with rest, her state will improve and she can avoid surgery. 

It's already late at night when the girls arrive at the hospital. They refuse to go back to their dorm and insist to see Yerin first. When they finally enter Yerin's treatment room, Yerin is sleeping, there's IV fluid hose chanelled on her left back hand. Mrs. Jung, Yerin's mother, is in there, she warmly welcome them and explain Yerin's progress, that after details diagnozed though her condition is not serious enough to require surgery, the doctors informed that she must have full rest as she will need to undergo surgery if her condition worsens, doctors will monitorize the progress. For now, the painkiller is help a lot to calming Yerin and make her able to sleep well, rest is really helpful for her healing process.

"I've been there too, Eomoni...  last month I've got appendicitis too. It was horrible pain, but after I got medical treatment at hospital I got better fast that I even didn't have to skipped schedules the next day. But if now Doctors even told Yerin Unnie to have temporary break time then it maybe because she really need it more than me before. I hope Yerin Unnie get well soon. It's gloomy without her around." Yuju expressing her concern.

Mrs. Jung smile, "Did she?"

"Yes, Eomoni. Yerin Unnie is always bright and cheerful, she also absolutely fun playmate and loving Unnie. We gonna miss her a lot for these few days onward..." Umji choke at the end of her sentence with trembeling lips and teary eyes, so Mrs. Jung pull the maknae into her embrace, soothing, "Awww~.. Maknae-ah..."

"Oh yeah, I just remember... Sojung-ah, Yerin ask me to tell you that if you come to visit then it's okay for you to wake her up. She need to talk to you." Mrs. Jung said.

Sowon lift up her eyebrow for a bit, anxious, "But Eomoni, you said Yerin need to rest, so how can I wake her up..."

Mrs. Jung smile wisely, "I just told you as my daughter asked me to tell you, I think she might gonna upset more if I purposely not tell you, eventhough as her mother indeed I prefer her to stay sleep since she really need it right now. But I'm sure Yerin has her reason why she insisted me to tell you that it's okay to wake her up because she really need to talk to you. Maybe because if she doesn't need surgery and Doctor permit it, I'm planning to take her home tomorrow, to treat her at home comfortably. Uhmm... then why not you sleepover here, Sojung-ah? then later or tomorrow when Yerin wake, you can talk to her. I'm sure she gonna be so happy having you here." Sowon think silently.

"Can we sleep here also, Eomoni?" SinB ask.

"No, you can't!" instead Mrs. Jung, it's Manager-Oppa who answer SinB's question firmly, SinB pout, sulke, obviously not happy with Manager-Oppa's prohibition.

In the end the girls have to except the reality that just Sowon who allowed to stay with Yerin and Mrs. Jung at the hospital, while the rest of members have to go back to their dorm. No matter how they protest and grumping, the decision will not change.

So then after the girls forcefully left with their Manager-Oppa, Sowon having warm conversation with Mrs. Jung. "Yerin told me that she feel guilty and sorry that she often not listened you weell, that she also often ignored your concern. She never thought before that her reckless way to ate would bring this 'so much pain' like today. She admitted to me that you actually often told her to be careful in everything she do, including the way she eat. She also confessed that you've been took good care of here since the beginning symptomps, eventhough you scolded her a lot but you still took care of her gently."

Sowon quickly respond, "I'm sorry, Eomoni." She said with trembling voice.

"What you are sorry for, Sojung-ah?" Mrs. Jung ask.

"For scolded your daughter a lot. Please forgive me." Sowon said as she start to sob.

"Hey... don't sorry for that. I'm not blame you. I know my daughter very well. I know how irritating she could be sometimes. If it me being you, I might already grabbed her hair and pull it roughly or twist her ear or at least spank her . Hahaha...!" Mrs. Jung chuckle, "It's me who supposed to be thankful to you." Mrs. Jung said warmly while caress Sowon's head dearly and gently wipe Sojung's tears. "Thank you for being great unnie for Yerin. She've been grown like only child in our family, since her with her older brother is quite far, we might misstreated her like princess, that make her feel so free doing anything she like in her own way. Fortunately, her dream to become idol, trained her to be able to discipline and tough. Also having you become her unnie and leader is another thing that we grateful. You able to fill the role as big sister that Yerin never had before, while the other members also fill the dongsaengs role that make her learn to share and become an older person that should be able to take care of youngers. All of you are perfect to completing my daughter to become whole and better person. Thank you very much." Mrs. Jung said with streaming tears in the end of her sentence, while Sowon is even more sobbing with tears that stream swiftly.

"You are very good leader, Sojung-ah. Trust me. It's even hard for me to imagine how hard your struggle to make those 'cute beagles' to listen your command and even manage them to do everything perfectly as all of you supposed to do. You must have to restrain yourself a lot. You must have been through a lot of hard work and bad things. You must have tried uncountable effort to finally able to make them trust and follow your lead. Good job, Sojung-ah. You really have done very good job and I believe you gonna make another good job onward. Thank you for your hard work, thank you for lead and taking good care of my daughter. 

Please continue onward. I'm trusting my daughter to you. I'm sorry that I have to put that heavy burden on your shoulder when me and my husband as Yerin's parent are who supposed to be raising and teach our daughter on how become person who able face the world, but you instead who excellently fill that role in Yerin's life these latest 4-5 years and I believe more onward. Thank you very much, Sojung-ah. I'm trully grateful for you." Then Mrs. Jung pull Sowon into her tight embrace as she peck few times Sowon's head dearly --- by the way, Mrs. Jung peck as just like how Yerin's way to peck, kind of 'bombarding peck' ㅋㅋㅋㅋ^^ ----. Both of them crying and sobbing so much, but also had heartwarming feeling.

Few hours later... early in the morning.

Yerin wake and slowly open her eyes. The first thing that catch on her sight is the view of cute gorgeous sleeping Sowon right on the front of her face. They apparently cuddled along for Yerin don't know how long have been, but she just can't help to feel glad to see her roommate by her side.

Yerin elongated her neck to give a peck on Sowon's nose tip, that make Sowon wriggle a bit then awaken, open her eyes in cute sleepy way.

"Good morning, my Gorgeous-Unnie." Yerin greeting in half voice, just enough for both of them listen, with happy smile plastered on her still-pale-face.

"Good morning, Yerin-ah. How's your feel right now?" Sowon greet back and ask in concern.

"Better. And I'm so happy to see you here." Yerin said still with smile that seems won't go away easily.

"Good to hear that." Sowon said back also with warm smile. "Eomoni said you want to say something to me, that's why she told me to sleepover. What is it?" Sowon ask without beating around the bush.

"Uhmmm... I just want to apologize for ignored your concern and for rebelled your words, when I actually know that it's all for my own sake. I realized that I just low unto myself. I'm sorry, Unnie. I admit this terrible pain that I had was because my own fault also for not listen and do as you told me to do. I also want to thank you for still took care of me even after I've done irritated things and such an ignorant to your kindness." Yerin said in guilty tone.

Sowon caress Yerin's head dearly, "I'll forgive you... just if you promise me that you'll listen to me, not rebel anymore, and do better to me after this."

"I promise." Yerin said confidently.

"Great! So please fulfill your promise." Sowon beg.

"I'll do my best." Yerin said again.

Sowon smile, "And please get better as fast as you can. If you not around, then who's gonna help me herding those naughty beagles?" Sowon said in miserably begging tone and cute pout that successfully make Yerin chuckle.

"Awww~... my poor Unnie. You'll be fine. You are So-Jang-Nim (쏘장님 : The Great General So --- 'So' from the first syllable of Sojung or Sowon name), right?" Yerin teasing while in the same time couraging.

"But still... I need reinforcement. Without you I just 'toothless general' who miserably facing those savage beagles." Sowon whine.

Yerin laugh, "Oh... I thought I'm also one of those savage beagles?" Obviously teasing.

"Huft~..." Sowon deeply sigh, "Indeed, that's true... you are the big boss actually..." teasing back.

"Yah!!" Yerin slap Sowon's arm, pretend to irritated, but she did it while laughing.

Sowon laugh too, "Yah?! How dare you 'Yah!' to me?! Who do you think you are?!" Then Sowon pinch Yerin's cheek.

"Ouch...! ouch...! okay, okay.. I'm sorry, Unnie. Ouch!" Yerin begging for mercy, while Sowon still laughing.

"Ouch! Stop it, Unnie. Hahaha! Please, stop making me laugh. Doctor told me that I better keep my stomach in calm to reduce the pain. It's hurt if shaking too much. Hahaha!" Yerin begging between her giggle.

But Sowon by heard that, stop laughing instantly, "Oh.. I'm sorry. Is it hurt so much? I'll call the doctor."

Just when Sowon about to get up, Yerin stop her by hug her tight, "No, no! Not necessary. Just stay here with me, Unnie."

"Are you sure? You said it hurt..." Sowon ask in worry.

"Yeah. I'm sure. Just stay here close to me." Yerin reassure. Then Sowon staying.

After a while... they turn to silent. Drown into their own mind while ruminating each other existence.

"Really... I'm so sorry, Unnie.... and thank you very much. I'm so grateful to have you. I love you, Unnie." Yerin said in soulful voice.

Sowon smile, "I love you too, Yerin-ah. Just get better fast and back to me as soon as you can."

Yerin nod with wide smile and teary eyes. Then they hug each other tight, not aware that Mrs. Jung is actually there, silently heard all their conversation and witnessed their cute behavior to each other, can't help to feel heartwarming and smilling in tears.
