Chen Zhiyu knew that he had to do a mission since he had memories. He did not know what was waiting for him at the end of the mission. The system told him that no one would want to have a memory gap that belongs to him but has no memory. Before he lost his memory, he asked the system to help him retrieve his memory through the mission. But he obtained an old attack in mission after mission.
Intention: If the lost memory is not recovered, then I will accompany you to create memories together.
