Hi everyone, since the bug where everyone lost their lists, I've never been able to find this manga again, even after digging through tags like murderer, yakuza, psychological, etc.

Here's everything I remember (some details might be slightly off):

- It was a black and white BL/Shounen-ai manga (it wasn't explicit).
- The two main characters were a super manipulatrice blond guy and a dark-haired guy.
- Everyone thinks the blond is the son/heir of a yakuza family, but later it's revealed that he actually isn't (The real heir was depressed and basically let the blond attend high school in his place so he could stay close to the dark-haired protagonist.)
* There was a brother with long black hair and a very distinctive diagonal/asymmetrical haircut. At first he hated the blond because he thought he was his brother (and he didn't like that his brother was stronger than him, or something like that??) , but after learning they weren't related he was relieved.
* The blond had killed his parents and buried them under his house and he also kept a guy in his basement and killed him
* There was also a really weird girl but I honestly don't remember much about her.
*The dark-haired MC later realizes the blond was actually the little blonde girl he knew when they were children.

The manga was still ongoing when I read it.
Does this ring a bell for anyone? I'd be incredibly grateful if someone recognized it!
