After taking Sungchan out from Haechan's school and telling everyone that he went boarding school, Kun thought it was probably better to get his brother help

You're probably saying that it's just a normal crush, but having a panic attack over someone anytime they're leaving or not around u, shouldn't be taken lightly

After a year or two in therapy
Sungchan was a teenager now  so he did a lot of talked with a lot of therapists, so Kun thought he was getting better but one evening Kun came into Sungchan's room and saw that he had pictures of Haechan on his desk. Kun was the school doctor so he knew that these pictures was taken not to long ago

"Sungchan what is this!"

"Hyung, why are u in here?" Sungchan said as he got out from taking a shower

"Sungchan answer me!"

"I-i don't know what you're talking about"

"Why do u have pictures of his boy?!"

"This boy?"
"Really hyung! I know for all these years u tried to make me forget about Haechan but pretending u don't know him, really!"

"What have u been doing? How do u know he goes by Haechan now?!" Sungchan don't know if he should say anything, the things he did just to be close to Haechan is things that shouldn't be said out loud

Kun sat down on the bed and held his head "I thought the therapy session would work"

"Stop it! U tried to keep me away from Haechan so I don't get too attached to him, but I still need him, no... I want him"

"Sungchan u don't understand, your health is at risk"

"No u don't understand, my health was at risk the day u kept me away from him!"

Kun was thinking it through, maybe Sungchan was right

"Hyung, u lied to everyone, even our parents don't know I go to therapy session, but you're going to fix it now, I want to go to school with Haechan and he'll be my boyfriend, I'll make him happy so I need u to fix this"

"No I'm sorry but I can't"

"What! why?"

"Haechan have a boyfriend already and they are really happy together, I can't break them up because of u" Kun was about to leave but Sungchan threw pictures on the bed

Kun eyes widened "Is this Mark?"

"With girls" Kun kept looking at the pictures "they have been dating for almost a year and I caught him cheating"

"But Ten trusted him"

"Kun, you're dating his brother and u know how much Ten loves Haechan so I need your help"

Not just because he's dating Haechan's brother but Kun loves that ball of sunshine so how could someone cheating on him, it made him mad "Ok I'll help u"

It took some time for Sungchan to think about a plan to expose Mark but he did came up with one and that was to get Haechan's number and text him the pictures but getting his number wasn't easy

It took Haechan two days to go back to school but he still didn't want to break up with him so Sungchan texted Jaemin and he did exactly what he was hoping

After 1 week since the break up Sungchan came into the school but something didn't go as plan

Mark still wanted to get back together with Haechan, but why?

Sungchan thought after Haechan broke up with Mark, he would just leave and go to some other girl but he didn't

So why?
