Yaoi ?or shojo ?

This sounds cool

I prefer shojo but yaoi is fine as well

Well I feel bad for whoever ends up in our world 'cause its competely crap

Here's a short list that I literally just put together. xD

It's kind of a mix though cause it also includes like traveling back in time.

I also have this list it's not really reincarnation but the mc being strong although I might have some mixed in with it.
