By Coincidence, My Naive and Rich Youth

I am Shimizu Mitsuhara. I missed the start of school due to accidental amnesia. After receiving rehabilitation training for about a month, I "really" became a high school student. In high school life, let alone January, in less than a week the classmates have become familiar with each other and have their own small groups. Naturally, it was difficult for me to blend in with my classmates, and I was misunderstood by them. "Will my youth end with this boring high school life?" I held my chin in my hands, feeling helpless. "I can help you, how about that?" The person who said this was the transfer student Haruka Hanyu. How could she be kind enough to help me? "Huh?
