TL Title: My body was replaced by a rotten girl 1 (part of a 10-volume series)

Lovingly harvested from: https://renta.papy.co.jp/renta/sc/frm/item/122871/

My body, which reigns at the top of the school caste and is refreshingly handsome that both self-acknowledge, and the body of the class's creepy rotten girl was replaced.
The rotten girl who took over my body said "I want to play with handsome people and BL" and say, my important best friend, strong-faced Yankee, school teacher, and finally put your hand on my brother! ?
On the other hand, I have become a fat and ugly rotten girl, and I am treated coldly by people who have been kind to me so far, and I will taste the horror of the world.

He somehow manages to return to his original body safely and try to repair his relationship with his best friend, but it's already too late... Huh? Will I be fucked this time?! Enough already! (crying)
