Hooni's finally starting to see that he needs to try and improve himself if he wants anything in life, as well as getting the motivation to at least try and stand up for himself.
Of course, we know he's the type to get overconfident easily and fail because of it, so he could go too far too soon (he doesn't even know her name yet). The girl seems like a good person so, hopefully, she'll still be nice to him even if she turns him down.
This could either be a major turning point for him, or completely blow up in his face. We'll see.
