Naww he gay and a murderer. What else?
after i commented this i’ve done some digging, so back in chapter 17 he said he fell in love with a person back in high school and now he’s dead, this manga is actually a spin off of “ Trace: Kasouken Houi Kenkyuuin no Tsuisou” in trace dan is the villian along with his friend who’s a dude and back in hs someone said that they bully ppl, and apparently that’s the person he was talking about. also in https://sexypedia.fandom.com/wiki/Hiroki_Dan#:~:text=There%20is%20a%20telling%2C%20though,expressed%20infatuation%20with%20anyone%20else.
below “Questionable LBGT rep” it says “ There is a telling, though ambiguous hint that Dan's first love (and possibly the first time that he felt homicidal intention) was a man. This love is the same person as the deceased friend. He has never expressed infatuation with anyone else.” so i guess he is gay but he doesn’t feel any attraction to anyone else but his first love (lowkey sounds like a love story if u remove the craziness ahahah)
Real also in ch 1 he also said that he's doing all the killings (he calls it a "good deed") to go to heaven to meet his friend. Possibly referring to his first love and also I think he's doing all of this murders because he failed to kill his 1st love with his own hands and now he's trying to make up for it or as I call it satisfying his needs by killing the others.
there’s also a hint in chapter 18! before he starts dancing in front of the teacher, he talks about dancing the oklahoma mixer on a highschool field trip where he says, “at my school, there were a lot of boys, so there were a few dance pairs that were both male. so with my first love …” and then he starts dancing tb ladida didaa LOL
so along with the other clues mentioned, the ambiguity lessens and i think we can confirm it!
More drama
