A young boy meets a gentle female teacher, and a heartbeat begins quietly on campus. The gap between secular ethics and status lies between the two people. The restrained feelings secretly grow wildly as they get along day and night. They try carefully, but in the end they cannot escape the shackles of reality. The love is sincere and passionate, but the fate is shallow, and the deep love that spans the years can only end with teachers and students. It ends with regret, and they spend the rest of their lives in the sea of people.
