xiao is your brother's best friend, with whom you soon became close friends, and perhaps even more. your brother, seeing his courtship, forbade you to communicate and lectured you about what a strange person xiao is

"you wont leave me, will you?"

he said, hugging you tightly

"it makes me sad when your brother tells me what to do, my own best friend.. I dont know, is he my friend after that after all..."
