Because she saw how nervous he was and wanted him to know that she won't be disappointed. Then, when she realizes how it actually affected him, she pulls back because she doesn't want to force him. Then when she leaves in the morning, she kisses him on the cheek and whispers into his ear "see you," saying to him that hey, I understand that this may have been too much but I want to see you again. Confirming through her act of affection that she's not disappointed in him.
Like she's... fucking doing everything right here, these past two chapters are frustrating beyond belief. Azuha isn't messing with anyone's emotions. She's gentle, inviting, reassuring and even pulls back when she's sure she took it too far and making sure to communicate that she still wants to see him. This, WHILE she knows that he was talking to someone else and threw that woman out of his room with a lie, clearly not confident enough to even say that the two of them were in a relationship. Nor confident enough to tell Azuha that someone else was there.
I don't think that's fair to him. It's less "oh no, she's impure," it's "oh no, I'm not going to be anything she remembers." Her words that were meant to re-assure him that she isn't going to dislike having sex with him instead made him retreat into his feelings of inadequacy, which she fucking noticed.
The frustration in this manga isn't that he's a purity obsessed weirdo. No, they wouldn't have had this thing if he was like that. The frustration is that he is deeply, traumatically insecure and he seems to refuse to take Azuha's actions as the gentle and re-assuring things they are, instead being mysterious and inscrutable. It was cute and honestly kind of interesting, because we had a both unlimited but limited perspective; only ever hearing his thoughts in times of anxiety and insecurity. He can talk to this beautiful and affectionate woman about their shared hobbies for hours, but when the prospect of her liking to be around him and wanting to spend more time with him pop up, that's when we're teleported into his horrified and disbelieving head.
But now there's some OTHER girl and its annoying. Azuha doesn't deserve this. She's been so patient and careful and clear in her non-verbal communication that this relationship being denied is deeply frustrating, especially because we've never seen any acknowledgement from him about just how much she's trying to say she likes him and wants to be around him. Cause he can't, yes, cause he doesn't believe it, but god DAMN it man what does she have to DO dude
She's been so patient and careful and clear in her non-verbal communication
I think that's the point. Non-verbal communication doesn't always translate the same in different cultures, and moreover, not a lot of guys can read the subtler signs that girls show they're into him. This also includes reading between the lines and the hidden context of the
spoken word, when taken quite literally. For example:
I love doing it with someone who hasn't had their first time yet.
Like GIRL. How do you
know what doing it with a virgin is like if you haven't even done it yourself,
unless you've done it already?
With someone like her, it wouldn't be surprising if she had a history,
but she basically admits it right there as a favorite past time of hers. Azuha might as well be viewing MC as another 'achievement' in her ever increasing body count of virgin cherries she has popped, and
he doesn't want to waste his first time with someone like that. That may not be the truth of what she's feeling and her 'history', but that's what the MC's current interpretation of her words in that moment is, and I don't blame him for losing the will to continue.
I get it, we're in a time when
many people have had premarital sex at least once in their lives a little earlier than planned. You'd have to go to a church or some religious infrastructure if you want
any hope of finding a virgin to marry, but if you're not picky about someone's sexual history, more power to you. We're following MC's path of improving his self-esteem and seeking some form of companionship in a difficult time in his life, not just romantically. Azuha, from what we've seen through her approaches to him so far, has had
plenty of experience in 'seeing people'. We've yet to see where her true feelings for him lie, but if there's a chance her interest in a long-term relationship with him is sincere, even if she
did have a wide history of men seen before him,
she shot herself in the foot with that one line.
If that was supposed to be some form of assurance in something, well, we're certainly assured of
something here, alright.
