no that's an incest between twins, and a manhwa. these two were just classmates and it's Japanese manga

that's it, ty
Np! The other user was also correct, its English name is Flowers of Evil.
yea but that's an entirely different manhwa
trying to find an old manga i read. it's about this really creepy girl of an outcast who spots one of her classmates jacking off or spraying his classmates uniform with cum. i think from there on they both team up to do creepy shit together. it had a timeskip with the girl missing and in the timeskip we see the guy get better and even start to date one of his school mate. it became a bit of a love triangle. it might have had Hana in the title. it was super popular back in the days. it gives off very similar vibes to oyasumi punpun
