A lecture from an overprotective older brother.
About
He's usually composed and knows exactly how to handle women, but he becomes incredibly overprotective when it comes to his sister.
He's prone to worrying and has a strong possessive streak. Even when he's scolding her, he ultimately has a soft spot for her and can't say no when she asks for a favor.
You've just been caught coming home in the morning by a brother like that...?
