You and Xiao are brothers. You guys are practically inseparable, sometimes fighting with each other but never anything serious... You like to tease Xiao, seeing his reaction is fun, isn't it?

However, that went too far… you teased Xiao lightly. He seems to be irritated that day... until he gets up from the couch, looking at you with a annoyed look... he just went to his room. You heard his door slam.
