Hello! Spank

A punk that causes memory loss by chance. Everyone calls to bring back memories, but it has no effect. The doctor said, "I'll remember everything in time. Sometimes it takes a day, and sometimes it takes many years..." And a heartless reply. Aiko takes her home and desperately asks Spank while showing her the album. But there is no response at all. At that time, Ryo thinks that his memory must return when he is shocked, and he struggles to surprise Spank, but will his memory return to his original memory?
