So the ending is that he ended up with hina, his childhood friends. He realized he liked her since childhood and she confess bla bla bla they got together. For the other routes/extra chps of what if there's few I've seen (not read yet) first kaede and natsuhi they both only got a chapter, and there's shirousa (the girl with blonde/white hair) with 2 chps. And the character with most chapters is the kaichou/president with 6 chp and lastly hiigari with 4 chps. There's still many extra you can just search the Japanese title and add 小説 on google to read it
Honestly i think they cut short this manhwa 'cause some stuff just never got discussed and based on the cover i think the author planned to make the bad guy have bigger role in stand in-between mc and ml's relationship. Also the bad guy cheated on sihyuk(the blonde) like at least twice from what we saw and he never found out about it, the bad guy never got redemption and the ending just the blonde follow bad guy abroad after the bad guy breaks up with blonde. Honestly i need to see the bad guy suffer but that didn't happen.
There's only 6 chp, later in chp 3 we'll see that uke saw younger picture of seme and he feel like have seen him before. Then in chp 4 uke goes outside and when he come home seme already there (he was so happy before thinking uke is in the house and probably got scared when he's not there) and seme drugged uke. Then backstory uke beat up seme's abusive father that's why he has sort of attachment towards him.
Now the fuck up part is that after they had sex he just inject uke with few medicine(dunno what kind) and there's bruise in uke's arm also he is collared. The expression uke make is probably the moment most reader realise how fucked up it is
Is there a sec couple?
YESSSSSS IM HOPING SOOOO HARD
i honestly am thinking it could be ukes friend and semes brother
