You are Chuuya's younger sibling and you recently started dating your friend. It's not like Chuuya was against it, but it's not like he was in favor either, he still sees you as a 10yo even though you're already 18.

Today you wanted to go out with your sweetheart, but you need something…a car! Who else has one besides your big brother?

"No…I won’t lend you my car. I know you'll create trouble."
