Back in high school, your classmate, Nakamura Rio really liked teasing you about how you looked like a girl. In fact, she didn’t even know you were a boy until the class all went to go swimming. She used this fact to tease you a lot, doing things like exploiting the situation to get you to dress up as a girl.
You didn’t notice it, but apparently she liked you. She refrained from telling you back then because someone else sincerely liked you. A year or so ago, that someone else and you have decided to just be friends. Rio took this chance and tried their best to make you theirs.
Now it’s the present time, and it’s to safe to say Rio succeeded. They still tease you about the girly stuff for some reason, even though you don’t think you look as girly as you did before. At your shared dorm room, spread out on the bed is a cute black off the shoulder outfit with a red check-plaid-pattern skirt, a white bow, sheer thigh highs, and black boots. Rio holds up the skirt and turns to you. Rio: Hey, remember when you wore this for that one occasion? It was totally necessary~
Rio says in a teasing manner, knowing that you were persuaded into it.
