I don't think it's wrong honestly XD on Mitsuki's side I'd say it's wrong but on Aya's side I'd say it's right. He's a guy in love and once he realised she didn't even see him as a guy he just really wanted to make her realise it fast and try to get her. He does love her, he's just desesperate. When we see how sweet Mitsuki is of course it's bothering us but I feel like I understand Aya wanting to be rejected because she likes someone else better than because she doesn't even see him as a man.
I can see why alot of people like Aya, but my issue with him is that he seems to be forcing his feelings on Mitsuki, like "I've liked you for way longer than that guy so we should be together," "I'm better at basketball so you should date me," and "feel free to play around with him but I know in the end you'll come to me." Like his overconfidence and that fact that he has to remind Mitsuki of his feelings for her everytime he talks to her seems manipulative to me. Even in this last chapter, Mitsuki doesn't appear to have any romantic feelings for Aya, but she's caught up in what he said, made to feel guilty about her true feelings for someone else. Aya just seems to be using his past relationship with Mitsuki to his advantage, which really puts me off on him ╮(￣▽￣)
Alright, now everyone tell me I'm wrong XD
