He Ci - His parents died early when he was young, and he was brought up by a neighbor's aunt. He grew up with "call tasks" since he was a child. Every other week, he will receive tasks and must complete them, otherwise he will be punished. Generally, the time limit is one week.
Liu Ruo - a sultry man who doesn't like to talk. He has the same call task as He Ci, but the two of them don't know it. He talks little, but he talks more when he meets He Ci.
The two of them didn't know that there was someone else besides themselves who had a call mission. Although they had seen each other in the call world, they didn't dare to recognize each other in reality.

"Afraid? How strong were you in killing a bunch of monsters in one go?"
