I need to find a guideverse bl manhwaaa

So like the top (probably) is like the strongest esper and he loses his mind and becomes unstable asf, he wasn't really sweet when he hadn't lost his mind. So after losing his mind he also loses his memory and so there's this guide who is there to guide him and nobody wants the esper to get his memory back as he could be a threat to humanity....it has a similar art style to alot of manhwas but maybe netkama punch or guild member next door, i read a longg time ago so i can't recall properly.
Ps. I know its not dear 00
