series is Hajimete no Gal. it's mediocre because it's a 200 chapter long ecchi romcom about a guy almost but not quite scoring over and over and I'm not going to stick with that
the two bits that stuck with me are the heroine's main concept hook and one individual bit
basic premise is that a horny otaku boy is coerced into confessing to a trendy gyaru but then she accepts the confession, hilarity ensues
the heroine hook is that the protagonist is doing all these over the top horny virgin machinations and constantly terrified that she'll discover how cringe he is and mock him and dump him and make fun of his tiny penis or whatever
but instead she's just, genuinely a really likable chill person without a judgmental bone in her body so she no sells all of it
the one bit is, a friend gives the hero a pair of movie tickets to try and get him to invite her to the movies
and whether or not he does becomes a big stupid asinine drama, but eventually he does it
except, the tickets were in a little envelope, and he had never opened it to check, what the movie was

a spinoff movie for a magical girl anime aimed at third graders
obviously she immediately counters his meltdown about it by going "sure is sunday cool"
and the punchline is, while he's worried about his inevitable humiliation

she gets so into it that she's crying and yelling at the screen along with the seven year olds
sometimes precure just be like that
not gonna lie, that's at the very least my ideal kind of person. Someone who can enjoy whatever life throws their way.
Honestly I feel like gyaru are often portrayed like that as a feature of the subculture
there's an older expectation of like, mean bully girls who make fun of you for being an otaku
but yeah gyaru have gotten kind of an optics shift
Marin Kitagawa is definitely part of the newer gyaru portrayal, I think the girl in See You Tomorrow at the Food Court is in a similar vein
and at least the early parts of this are sort of playing on that shift
where the otaku loser lead expects the old style and instead he got the new style
