"Liking ships with two or more minors means you're sexualizing them."
No bitch, I want to see them hold hands, do awkward teenage things and hug. I want to see them be sweet and comfort eachother when they're sad and need a reminder that they're doing great.
Kyouka: Friendzoned and friendzoning
So. Jirou seems to be the female classmate who the majority of 1-A's guys are most comfortable with.
However, contrary to my headcanon about the most popular 1-A guys, I feel like most of them aren't romantically interested in her.
It might sound a bit sad, but I headcanon that her miffedness about Mineta not naming her among those female classmateds that he wanted to perv on, is not entirely unwarranted... although, having Mineta salivating over you, is probably not something that anyone with self-respect should desire.

I can see her having gained some male admirers outside of the hero students, after the cultural festival.
At first sight, it might seem that Hagakure and Ashido are the most romance-focused girls in 1-A. However, supplemental and canon materials have depicted the tomboyish Jirou as being conscious about the male gender, the most:
During 1-A's practice match against Togata, she was the only girl who completely freaked out over his nudity.
In one of the drama CD stories, she made a big deal inside her head about holding onto the hem of Tokoyami's uniform, when they visited a haunted house together.
In one of the gag comics, she thought that Bakugou was self-conscious about holding her a girl's hands, when he wasn't actually. She basically just self-projected onto him.
In several of the gag comics, Jirou has been depicted as being self-conscious around Kirishima: One example has her perving on him in his costume. Another one, that retold 1-A's trip to the mall before Deku got accosted by Shigaraki, has Jirou imagining being on a date with Kirishima, when the kids paired up to look for Deku... and be pissed, when Kirishima dropped her at the first sight of Bakugou.
Ironically enough, she displays none of that awareness around guys who were hinted as having some interest in her: Kaminari (and I think, I've read something somewhere about Kouda liking her since their practical exams?)
Oh Jirou. You're definitely among those 1-A kids, who have the most growing up to do in the romantic department.
...
I just noticed that, except for Togata, all of the examples above include guys with whom Kaminari is explicitly friends with.
And now I headcanon poor Kaminari getting friendzoned by Jirou until at least until graduation.
The irony of 1-A’s resident flirt being canonically the first one out of all of 1-A’s boys who recognizes that he had fallen for someone: The girl, who just goes through successively crushing on all of his close friends... Now who's the flighty one, huh?
Yes, I imagine the unrequited love switcheroo trope, where Jirou won’t be able to recognize and acknowledge her own feelings for Kaminari for a while. She starts to consciously takes notice of him as a romantic prospect - juuust right when he's about to move on from his own feelings for her.
Drama ensues.
