So how does it end. I cant find the correct last chapter.

i’m pretty sure season one and two are like the “main story” and then season three are side stories, more so focusing on sub plots and sub couples i think? if you look at the .5 chapters, it kinda explains it a bit. the official ending is chapter 99. the author (fargo) did say that there will (probably) be other stories (like byul when he’s older and focusing on dojins sister) under a different name (kinda hoping for GL tbh) although i, myself as an artist make a lot of plans for projects and never pursue them so only time will tell
