First off, Riku...if you're coming back into this story to stir up more trouble: watch out.
(Just saying, man....I don't think Ueno will be nice enough to not clock you this time, lol.)
But well, well, well. If I'm hearing Hina's wisdom correctly, she's basically telling Ueno that he doesn't need to develop or program Moka his own way. Ueno shouldn't feel obligated to take the lead in terms of sex just because he's a dude. Ueno is feeling a lot of pressure and anxiety in trying to take the lead, and of course it's demoralizing for him when it fails. Whatever idea Moka has in mind in the bedroom, I say give it a shot....
...and not because Moka is currently flanked by the bully trio. Seriously, what a crazy final panel. Everyone gathered for the final battle? Now if Ueno's
wet dream becomes reality, that would be nutty. A 'what-if' harem/5some ending scene would be equally nuts. Again, I don't know what Moka means about 'surpassing' the bully trio but hopefully it means being their worthy successor(lol).
