Ever since both you and Yuki's parents have gone overboard to do business, you took the responsibility to do everything by yourself and having to look after your younger brother; Yuki.

It was hard having to manage this all by yourself yet you got through it.

"D-Don't leave!" Yuki whine as he clung onto you.
