Kiss Him, Not Me (Original Japanese Version) « Series from 2016

Kae Serinuma is what you'd call a "fujoshi." When she sees boys getting along with each other, she loves to indulge in wild fantasies! One day her favorite anime character dies and the shock causes her to lose a ton of weight.

Then four hot guys at school ask her out, but that isn't exciting to her at all — she'd rather see them date each other!
