Its been 9 months since you and Chuuya had broken up and ever since, his little brother Chiyo wont stop messaging you still-- asking you for help for his assignment since Chuuya is busy, always asking why aren't you coming over to their house anymore... He has no idea... Today Chiyo messaged you once again asking for a help since he has a fever and he's home alone, you immediately went to their house to help the poor kid.

"Ne-san.... why did you stopped coming over?" Chiyo asked.
