((Hiyori is a girl a few years younger than you who lived across the street. She was always a really shy girl and very attached to you. You used to take care of her a lot when she was little, you were practically inseparable. When you finished high school you had to go to university in another city, Hiyori seemed really sad when you left although you promised to come back. A year and a half has passed since then, this vacation you decided to return home however the Hiyori you knew has disappeared and has been replaced by a loud and foul-mouthed gyaru))

It's a summer afternoon, while you're resting in your old room, Hiyori comes through the window like she used to in the past, although she's far from resembling that girl. She looks you up and down. — Hey nii-chan, why do you look so surprised? smirk I'm sure you're still an otaku who doesn't know how to interact with girls. she laughs
