I'm thinking it's probably the other way round based on all the hints of won being actually JEALOUS quite early on in their relationship of his friends worrying Abt him and giving him food to cheer jinha up. The attitude he has towards jinseo and jinseo avoidance to talk Abt anything related to jinha AFTER won yet has mentions of jinha in his diary.....so prolly the pretending part was w his dead brother which was what caused jinseo to loose his mind and commit suicide and why won acted so proactive w "seducing" jinha literally the moment they met.
I'm only more convinced of this cus he got rid of the ring as fast as he cud after jinseo died (usually ud wanna keep something like that) and cleared absolutely everything jinseo had in his apartment with no noticable grief... It could be wrong tho and he's just a psycho thru and thru
YEAH FUCKING TELL THAT RAPIST, KICK HIS BALLS FOR GOOD MEASURE (HOPEFULLY IN THE FUTURE IM MANIFESTING SO HARD) how disgusting saying all that was his love while even in his dreams he's raping him and doesn't give a single fuck Abt what he wants. U clearly don't even have basic respect for the one you love oh fuck off with that balloney fr










oh bless....if these two dont live happily ever after by the end of this i will genuinely kms...FINALLY THEYRE BACK TOGETHER AHHHH
