no literally. after all the implied chapters and the extra content, he ends up with his sister? the FEMALE version of him? and its not like she's an awful character, but they fact that they just tried to fit it all the "chemistry" in one arc for ts when it would have been much more satisfying if hooni ended up with soorim.
i remember reading this manhwa before 2020, maybe even 2018, before it was serialized on l/zhin m. at that time i know it might not be confirmed end game, maybe an implied "oh they're living together as roommates in the future" but when this got officially serialized i think that's when soorim suddenly got a sister. saw people complain about it in other forums too because i was so shocked after coming back to this manhwa after years.

what do you mean he's gonna be with soorims sister? after EVERYTHING you implied, that there was something between hooni and soorim??? I'm hearing you even made PORN of them bro why are you cockblocking yourself like genuinely
