I'm looking for a comedy, romance oneshot (I think) about a boy with heterochromia (difference in eye color) who was bullied by a group of kids as a child and after a couple of years he comes back to get his revenge but one of the girls that bullied him fell in love with him and that's about it.
I tried the heterochromia category but I couldn't find it. Thanks.

There's a similar story to this but the boy doesn't have heterochromia. Yuuwaku - Sakaraenai Yokubou - 8) Sepia-colored Secret Room by HARUSHIRO Amami

That's it. Thanks a bunch. I remembered there was something about his eyes but obviously I remembered wrong what it was. Thanks again.
