Simply for mocking Makoto's early death, she was cursed by him and transmigrated into the body of Izumi Masamune. There's only one way to break the curse: to win over every anime heroine she encounters, despite the obstacles posed by the original protagonist and various other unforeseen circumstances. Megumi Kaname, Utaha Kasumigaoka, Eriri, Sagiri Izumi, Yukinoshita Yukino, Mafuyu Kirisu… Thus begins a story of youth, romance, and incidentally becoming a light novelist.
The principle of 'quantitative change leading to qualitative change' proves this: as long as I fawn over enough heroines, I'll eventually be able to win over at least one of them. With this thought in mind, veteran simp Kitahara Kaede went further and further down the path of simping, only to find, upon looking back… that all the heroines were actually secretly in love with him?
