I wait for the one time that she is so horny that she forgets they are in public and while he confesses she says by accident she loves him. Would be hilarious...
...Huh. So, she has a rejection fetish? Interesting.
But I can see why he'd be afraid of confessing considering he knows her secret...And that's why I can respect him for still going for it. In the end, he got rejected, as he expected...But it turns out, she seems to get even more aroused from rejecting him. Why? Well...Maybe because she actually does like him?
That ending though. Well hey, I'm sure they can keep up this routine until she slips up one day and actually accepts his confession. I'd certainly like to see that.
It's almost akin to the proverbial clash between an irresistible force (Yuuto's determination to get Kaho to accept his confession) vs an immovable object (Kaho's fetish of getting seriously horny after rejecting a confession given to her). If the build-up of energies reaches critical levels, will the universe survive, or might we all go out in a blaze of Vanilla?
