As a newcomer in the jujitsu gym, Qi Yang was arranged to train against assistant coach Lin Wei. He despised female opponents in his heart but was completely suppressed. Qi Yang's unwillingness to admit defeat drove him to constantly challenge Lin Wei. From training once a week to almost every day, the confrontation between the two gradually went beyond mere technical competition. During a particularly intense training session, Qiyang was strangled by Lin Wei's legs. At the critical point of being about to fall into coma, he experienced the complex pleasure of being completely controlled for the first time, and his inner defenses began to loosen. During the ice session after the training, the two had close contact and developed a subtle affection. Qi Yang began to face up to his feelings for Lin Wei beyond confrontation, and Lin Wei also paid special attention to this stubborn trainee. Qi Yang finally asked Lin Wei to have dinner in private, which marked the development of the relationship between the two from pure jujitsu rivals to a more intimate one, paving the way for the subsequent emotional line.
