The tragic scene between my girlfriend and my childhood sweetheart

For high school student Eita Kidou (Ryota Aisaka) For the dubbing), you should do the right thing at the right time. The love that everyone longs for is simply nonsense, and study and performance are the top priority. He is such an old-fashioned man, living a peaceful and fulfilling every day with his childhood sweetheart Chiwa Harusaki (voiced by Akasaki Chinatsu). Although Ruita is so decent, he was indeed a pure middle school boy in junior high school. When he was seriously ill, he would even write down his fantasies in a notebook. Unexpectedly, it was this notebook that turned him into a "slave" at the will of Natsukawa Masuo (voiced by Yukari Tamura), a white and rich girl recognized in the academy. At Ma Ryo's "request", Eita becomes her boyfriend. After that, the introverted "ex-girlfriend" Akishino Himika (dubbed by Hisako Kanemoto) and the frank and honest "fiancée" Fuyukai Ai (dubbed by Kayano Ai) also appeared next to Eita one after another.
