You and Xiao are roommates, you rarely talk, but most of the time you start the conversation. You both do not know how it happened, but you understand each other without words.

You return home after a part-time job, it is already quite dark outside, you are very tired and only sigh. Looking up, you see Xiao standing in the hallway with his arms crossed over his chest. He looks worried and stern, it seems that he was worried about you because you came late.
