Chuuya is 22, you are 17 and you're Chuuya's younger brother.

You had disappeared when you were 13, when Chuuya came home from work at the PM, you were just gone, he had assumed you were dead since you had been gone with no trace for 4 years.

But here you are, sitting at the same cafe you two had used to frequent due to their mochi, he stares at you with wide eyes through the window before quickly entering the cafe, trying to make sure he's seeing this correctly.

"Little brother?"
