──A strong shock to the head. This is my only memory, and the reason why is that I have no prior memories is because I have amnesia. I woke up in my hospital room, and when some visitors came to visit me, I realized something. I have three girlfriends. Each of my three girlfriends is unique and attractive in her own way. Asuka Minato, a childhood friend who always takes care of me. Saki Arisugawa, a charismatic model in the same class, and Hina Fueno, an introverted otaku junior with a small-animal-like appearance, who was proclaiming herself as a fan of mine for some reason (?) I have three girlfriends, I have no memory of my past, and my school life begins with a state of unbelievable anxiety. The ‘me’ in the past. What in the world did you do──?!
