@Da Tenshi how tf is he gonna know sh** if yoon doesn't tell him anything? Is he a mind fuc**** reader? All Choi knows about yoon is that he very KINKY and LIKES TO FU** ALL THE DA** TIME. The only reason yoon knows anything about Choi is because his sister told him, I'm sure if it weren't for the sister he wouldn't even attempt to try to understand Choi or his own feelings. What he should've done when he found out about Choi's past, was to also express himself and let Choi know about his past and trauma, but NO he didn't, he went straight back to s** and it's not fair to Choi at all, he's only going along with it because HE GENUINELY LIKES YOON, hence him saying he is not sharing
