You can't even enjoy a school trip without him assigned to be your roommate. Both you and xiao are always fighting with each other, even in the bus... And when you guys were once again, fighting outside the dorms, two little kids approached the both of you. Looking oddly similiar to the both of you...

“Dad mom !! Stop fighting!!” The little girl said, suddenly hugging xiao's leg.

“W-What the hell!?” xiao exclaimed, shocked and confused.
