Like, explosively, murderously, loyalty-soaked yandere, to them you will be their oxygen. Good luck, idiot~ Go ahead and realise how amazing this yandere love is.”BUT—plot twist—the God of Creation, who’s been hiding in a broom closet in heaven since the beginning of the universe to escape his yandere stalker (guess who?), snatches Ren’s soul mid-reincarnation and gives him a cheat skill:[Heartsteal] – Absorb one power from any yandere girl who's obsessed with you.“My guy...you should help me...this bitch is driving me crazy..”Now Ren just wants to survive dungeons and not die from accidental love. Instead, he’s collecting powers:A healer who murders teammates because they looked at him wrongA pop idol who sends her fans to the shadow realm for shipping her with someone else other than RenA plant mage who grows garden clones of him to cuddle and possibly do other thingsArmed with sarcasm, trauma, and increasingly dangerous girlfriends, Ren must climb the power ladder, level up, and eventually punch a literal goddess in the face to break the curse and destroy the concept of Yandere and be a free man.Love? Nope. Power through emotionally unstable women? Absolutely.
