Long time ago I read a shounen ai manga which I can't remember what the tittle is. This is the synopsis: there was a boy (i forget what is his name) who had supernatural power which can kill anybody with just his sight. When he was a little, he killed his cat with his power (but at that time he didn't realize that he had such a strange power inside). He had a friend name shougo. His over possessive feeling through shougo cause he killed shougo's family. After he realized about the power, he hynotized himself so that hr could remember nothing.

If somebody knows about the tittle, please tell me right away. I'm so curious.... I'm available at line messenger and whatsapp messenger

Since I'm curious too...I'll give the thread a bump.

MU's description search came up with this manga, Kimi ga Kimi de Aru Tameni, but there are some differences...

Semi-retired.

Although I'm not the OP, I'd still like to say thank you. 🙂
