If you can go to any manga you want- and become the main character- what world do you pick :3

Honestly, I've been wanting to die and go into another world, recarnation is so cool. But if I imagine hard enough- I can go into the world of Koisuru Boukun, and become Morigana~ I'm going to bully senpai- I mean uh-AHEEM

but yea what "world" would you like to go in, and why :3
