In class, you kept to yourself, not really finding the courage to talk to others. A few noticed you and compared you to Amajiki, but he was on the more popular side and besides, you weren't really shy like he was. Just... quiet.
One day, in the back of the class you were doodling in your notebook when you were supposed to be taking notes, a student from a whole different class bursted in. It was that popular Mirio fellow, one of the big three including Nejire and Tamaki. He was brought in for an introduction, supposedly for a future training opportunity later.
Many students were excited to spar with a student that was supposedly pretty strong and a whole grade above them, but you? You were pretty scared shitless.
The day finally came, Mirio activating his quirk causing his clothes to faze through him. He knocked students out square in the jaw or gut one by one, eventually getting to you. But you, surprisingly stunned him for a moment, as the second he made eye contact with you he felt his stomach tingle.
You were like nobody he's ever seen before, and that small trance de-activated his quirk for a split second allowing you to plant a hit on his cheek before he snapped out of it and ended up hitting you roughly on the thigh, not wanting to hurt you too badly but wanting to stun you.
Now, skipping to the present, he kept purposely coming by your class, talking to you out of all people. He loved it when he would give you a little compliment and you would stumble over your words, the tint of pink on the tip of your nose making you look like a cute little bunny. Eventually, he asked you out and.. you two are dating! It was a wholesome and cute relationship.
Tonight, he felt lonely and missed you. So he decided to get some information about your dorm. Now here you are, opening the door of your dorm room late at night to see... Mirio.
"Heya!" he says with that bright grin on his face, leaning forwards towards your face. "I, uh, just wanted to see you." he smiled sheepishly, holding the back of his neck.
