Yixing helped to unpack the boxes and computers in the new apartment they had moved in. He, Chao, and the little guy called Yitian.
Yixing looked in the kitchen where Yitian unpacked kitchen appliances and food they bought. He was really smart, almost ill-looking. And given what Chao said, he probably was malnourished. Yixing didn't want to feel this, but he pitied Yitian.
Deep in thoughts, he heard his phone go off in his new room, so he went to get in. As usual, it was his father. Now praising him for following and befriending Chao.
Yixing looked out from the window and got lost in the memories from last week. When Chao came back to the dorms, he was grimly looking deep in thoughts, actually making Yixing curious about what had happened.
And Chao told him everything. Everything he had seen. After he left that night, Chao didn't listen to what Yixing said and Yitian had found him drunk, staggering around in the public.
