Baron Kitagawa Anshi came to the wrestling club to look for the "murderer" because his sister was pushed down the stairs. The head of the club, Ma Tangtang, stepped forward to confront him and was hurt by his domineering and cold attitude. The two of them were disgusted with each other. Kitagawa Anshi suspected that Ma Tangtang was the murderer. In order to uphold justice, he joined the wrestling club as a student. The two of them confronted each other and the conflict escalated. At the same time, the real murderer, Lin Feng, took care of his sister with guilt. The sister, who had a one-sided love for Lin Feng, enjoyed it and concealed it unconditionally. Poor Ma Tangtang was wronged and tortured, and the relationship between the two warmed up in the battle of wits and courage. Kitagawa Anshi gradually dispelled his doubts. The sister learned that Kitagawa Anshi was going to propose to Ma Tangtang, and she lied that Ma Tangtang was the murderer out of jealousy. Kitagawa Anshi and Ma Tangtang had a confrontation and parted unhappily. After learning the truth, Ma Tangtang chose to leave in order to protect Lin Feng and her sister. Kitagawa Anshi regretted it after learning the truth. On the day of the game, Ma Tangtang showed up by surprise. The two smiled at each other.
