Synopsis

V.1 - 17 Seito Arioka Yukihiro. 17 years old. A third-year high schooler. He is capable of handling things well and has good looks. That’s why he takes things for granted, knowing that it will end satisfactorily for him. Until… Mishima Makoto. 26 years old. A teacher. He lives his life diligently, sincerely, and while holding on to unspoken feelings. V.2 - 17 Kyoushi Arioka Yukihiro. 17 years old. A third-year high schooler. This is the first time I’ve seriously fallen for anyone. I wanted to make Sensei mine, so I forcefully took him. Mishima Makoto. 26 years old. A teacher. I’ve always had hidden feelings for my close friend. I thought it was a love that could only end with me giving up. Mishima, who once refused the selfish Arioka, began seeing his own unrequited love because of Arioka, who was not afraid of showing his feelings even if it meant getting hurt. V.3 - 17 Hatsukoi Arioka Yukihiro. 17 years old. A third-year high schooler. He forcibly took the first person he fell in love with and is now repenting and reflecting. He tries giving up, but even so, he couldn’t. Mishima Makoto. 26 years old. A high school teacher. He’s had one-sided feelings for his best friend and sees the pain of it in Arioka, which makes it harder to refuse him.
