Mina and Midoriya had never really started off as friends. They'd always been acquaintances with passing interactions, having formed their own groups in class. The biggest connection they'd had, really, was the fact that Midoriya and Kirishima worked out together pretty often.
However, when Midoriya offers to help Mina study after she finds herself stuck with academics, she begins to find out that there are quite a few ways to refer to her new friend.
And soon, one of her close friends.
And soon enough, one of her best friends.
And soon enough after that?
Well, maybe it's not just friends.
