Well, I'm quite happy to see a 4th chapter in this series.
I think it was pretty obvious when she was saying stuff like 'wanting someone to fall in love with me' that said someone was actually him all along.
He didn't seem to even clue into the fact that it might be him halfway through, but at least despite not knowing, he still tried his best to get his feelings across to her (even though she already likes him) so good on him. And it ended quite nicely with her 'making it up' to him.
