Honestly it’s between Oscar or Calix since she doesn’t have any chemistry with the other two or many scenes with them. The only reason I think it’s Oscar is that she seems to favor him the most, he was the most distraught when she “died”, and he’s also the first one to kiss her. So all signs are pointing to him being the ML, but I wouldn’t be mad if Calix was the ML either. He’s the only one of the four that emotionally grew and matured and only he apologized after kidnapping her.

Everyone is mad or hating this story but I actually quite enjoyed it. I’m really simple minded it doesn’t matter how average or bad a story is if I’m entertained then it’s good in my eyes, the art is also a plus although people don’t seem to like that either. ML is definitely Oscar no doubt about it but I’m not mad at it, he was my favorite during the childhood arc. Idk I think I’m just basic
