A few day had pasted after Tzuyun opened Chou's company, Chaemin have always been by his side as his bodyguard

"Chaemin hyung...can I talk to u for a moment?"

"Of course, what's the matter?" 

"There's a secret....between Sana and I"

"Sana and u?" Chaemin asked 

"What is it?"

"Promise me u wouldn't get mad at Sana"

"Ok I promise"

"Comfirm?"

"Neh"

"Don't get mad because Sana and I have be-" 

"are u guys secretly dating!?" Chaemin said a bit louder and got up from his sit 

"Yes" Tzuyun replied "But that was in the pa-" before Tzuyun could continue, Chaemin sent him a strong punch on his face

"U betrayed me? I'm your best friend!"

"Hyung let me expla-" 

"How can u do this to me!?" Chaemin said angrily 

"I didn't do anything to u"

"Betrayal!" Chaemin shouted 

"Hyung! I'm not dating her!" Tzuyun tried to explain but Chaemin walked closer 

"That's nonsense!" Chaemin gave Tzuyun another strong punch on his face "I should have known when Sana went to Han river!" Chaemin punched Tzuyun once again and it made Tzuyun's lips to bleed "how long as it?!"

"I really didn't" 

"How can u do this to me?!" Chaemin pushed Tzuyun towards the the wall "i-I'm your best friend" Chaemin wanted to gave him another punch but the door suddenly opened 

"O-oppa!" Sana called as she saw Chaemin was about to punch Tzuyun 

"H-how dare u?" Chaemin continued to ask Tzuyun while ignoring Sana 

"C-Can't u let me e-explain f-first?" Tzuyun tried to speak as possible as he can because his neck is being straggled by Chaemin 

"Oppa, can u stop?! He might die!" Sana ran towards Chaemin trying to get his grip off Tzuyun 

"ARE U SIDING HIM NOW!?!? HAVE U BEEN PLAYING ME!?" Chaemin pushed Sana, making Sana to fall down on the floor and accidentally hit the vase

The vase break and the tiny pieces of the glasses cut Sana's hand making her hands bleed 

"Ouch!" Sana shouted as she felt her hands bleeding 

"S-Sana!" Tzuyun pushed Chaemin down the floor and quickly went towards Sana even tho he is already in pain "a-are u ok?" 

"Don't touch me!" Sana pulled her hands away from Tzuyun's grip "U were trying to ruin our relationship didn't u!" Sana glared at Tzuyun "I told u not to ruin us! Didn't u ruin me enough!?" Sana shouted 

"I-I didn't...I just wanted to tell the tru-" Tzuyun was cut off by a hard slap from Sana 

"I don't want to see u ever again!" Sana shouted as tears ran down "u didn't changed a bit! You're still the shameless jerk five years ago!" Sana got up "let's not be friends anymore....it's useless, you're back because u wanted to ruin my happiness, i should have known the day u saved me" Sana walked away towards the door "Oppa, u should have trusted me....I will never cheat on u, I love you" Sana finally said those words before slammed the door 

"S-Sana loves me?" Chaemin whispered 

"Hyung...Sana and I really secretly dated....but that was five years ago" 

"..."

"U should have not be so jealous....u let jealous took over u" Tzuyun who is sitting on the floor continued "Sana loves u....but she never have the courage to tell u, she's hurt by me" Tzuyun let out a sad smile 

"..."

"Hyung...it's not to late to chase her now, I know she will forgive u"
