if it was helpful ٩( 'ω' )و

I didn't think this list would have so much followers. Thank you. For those who are asking if this list is active, yes its active. I'm just really picky.

What you'll basically see here:

Heroic Protagonist.
Trash Protagonist turned good.
Plain trash protagonist you can't help but like.
Villainous protagonist.
Cheat-like protagonist.

I'm biased with everything placed here since I read it all. I hope you like them too.
