I met my wife, Akari, when she was a student and I was her homeroom teacher. There is a 20 year age difference between us. Akari confessed her feelings to me when she was 18, but since we were in a student-teacher relationship, I naturally turned her down and didn't make a move until she graduated from university, and then we started dating. We got married when I was 45 and she was 25, and we're still together now. I bought a house so that Akari wouldn't be in trouble no matter what happened to me. One morning, I noticed something was wrong with my wife and took her to the hospital, where the doctor told me she had a memory disorder called dissociative amnesia, a type of memory loss.
