"You even let the principal touch your boobs".
This is my problem with the gyaru archetype.
I'm not stupid, I know myself, I know I'm the jealous type. And I just couldn't go for a girl that's just showing her bra and panties to everyone. Let alone touch her boobs. "It's not a big deal". Sure, that's fine. Get a bf who's okay with that. I wouldn't like it.
And just to bring it up one more time, "dense MC". In here at least she's honest and has actually confessed already (even if we've forgotten about it, fucking author). But many manga with gyaru/teasing FMC are like this. If she behaves like that WITH EVERYONE, how are you gonna feel especial? I would never think "she likes me". And not because I'm dense, but because she's like that with everyone.
Also, I gotta say the character progression feels stupid. She became a gyaru cause shebl thought they looked strong or something. Fine. I can accept she's okay with showing her underwear, fine. And even pushing her chest on random people, though it bothers me.
But how the fuck does she get embarrassed with an indirect kiss and then is okay with a random dude feeling up her boobs?
