[He can't help but think of a promise he's left unfulfilled back home, wondering if he'll be able to keep it one day. He has to, for the sake of his friend... for the sake of his friend's little sister, he has to. That was something he was forced into, and no easy task either, but either way he'll see it to the end somehow.
And it's no different here.
But he had his chance for her to take him seriously, and it's getting passed up.]
Listen, Pinky, I don't do serious very often, so if you want some promise you'd actually want me to keep let me know. Just know I'm not putting a shirt on, that's a given.
[And don't ask him to stop flirting with girls because it's kind of his only way to hide who he really is and keep all the serious inside him.]
Dunno, it can be something like 'Zaveid, come bring me breakfast everyday!' or 'Promise me you'll never ever make a lady cry'. Stuff like that.
