um he didn't really cheat?? it was kind of a misunderstanding on Siwon's part :((
How did he misunderstand can u plss explain cuz the comments are implying that he really did cheat, and from that question mark in ur statement it seems like ur not sure either sooo plss explain ╥﹏╥
spoilers kinda //
so basically he overheard his boyfriend practicing some lines for a BL drama with someone (which is the friend of the bf, Junseok i think) and so Siwon decided to not confront him abt it. it was Siwon running mostly from his bf and led to more misunderstandings. knowing the fact that Siwon's bf dotes on him so much and they had been together for 8 yrs already, it's kinda unbelievable for Siwon to know why his bf would cheat. BUT HE STILL DIDN'T WANT TO TALK ABT IT LOL. he ran away instead :) HAHAHA there i hope u get it ╥﹏╥
Wait did siwon bf like really cheated???? Ive been wanting to read this one and im on the 2nd chap but then i read some comments saying that the dude really did cheat... and if he did im not gonna read this anymore cuz as much as u try to justufy cheating it’s still cheating （￣へ￣）
