Can anyone recommend me more stories like this one?

juujika no rokunin

Yeah but it kinda sucks now from what I heard

It was amazing at the beginning

Exactly, the whole amnesia thing kinda put me off

I don't know if it'll fit what you want but maybe try "Ouroboros" ?

I already read it but thanks

Then "Funouhan"? I'm pretty sure you already read it too but who knows ╮(￣▽￣)╭ ( I'm all ear if you have any recc as well (●'◡'●) )

That's literally my favourite story, ughhh. Museum? If you already didn't read it.

From the red flag is also really good, lol. He is my favourite
