We met by chance at the library, but Moe Amatsuka seemed like a young man with a gentle and shy appearance who had fallen in love at first sight with Amatsuka. She is a female student with a beautiful innocent face, but a rather bold personality, so she proactively approached the young man to get to know him when she saw him secretly looking at her and smiling. The two had their first dates together, but contrary to that innocent face, in private Amatsuka revealed herself to be a lustful girl, with perverted and sadistic hobbies, which made for the naive young man who could only close his eyes to enjoy the new happiness that the new girl brought him.
