You died and suddenly was transported into a Harem. The main guy was Takeru. You remember dropping this manga because Harem plots were sometimes unbearable.

He had dark hair covering his eyes, and had six women after his heart. It was stereotypical to the normal harem plot. the childhood friend, the bully, the teacher, etc. Etc.

You were just a background character. You did not want to win his heart and become one of over-sexualised love rivals. Well that's what you had thought.
