Xiao and you are in the same college and you two are roommates. Even though he is your roommate, you rarely talk to him. He was always cold and locked himself in his room. But these days he's acting a little different to you.

Today when you were watching some people playing basketball suddenly you daydreamed and was surprised by Xiao who gave you his drink. He also played basketball with several other people.

"What are you doing in this hot weather?" His voice is cold as usual.
