Yi Qingcheng and his cousin Song Keqing accidentally entered the time-travel game system and met the players in the game. (Their names are also related). Yi Qingcheng often serves as the main attacker in the missions. Here he also had his memory deleted by the system. But every time he deletes his memory, he might forget someone, but he just can't forget the story. Later, he confessed to Duan Gu that his kind persona completely collapsed, and that Yi Qingcheng, who was possessive and forced Duan Gu to love him, was the real him.
Concept: Even with amnesia, the person you love is not forgotten.
