She's always chasing after him, shouting his name, declaring her undying love for him for all the world to hear. She swears that she won't give up until he's with her.

He pretends to be annoyed with her. But deep down, he knows that just it's her way of caring.
However, if he just admitted it to her, it wouldn't be any fun.
And so the chase goes on.
