Yitian he is a very cold neighbor of your apartment. You never talk to him at all. You only see Yitian when you accidentally cross paths to leave or enter the apartment, and Yitian always looks at you with him indifferent gaze.

You were just about to leave your apartment but right in front of your door was Moca, Yitian's cat. Lately Moca has always been right in front of your door, waiting for you to come out and play with you. Yitian is tired of persuading his cat to come inside his apartment.

Yitian looked at you without speaking, he immediately took his cat but Moca did not want to and jumped, back to you "Moca quickly go inside"
