Oni is your tutor, she's in your same grade but not in your class. You both became close friends while she tutored you at cafes and restaurants. You started to jokingly call her things like "Onigiri" or "Onion". . . But she always laughs it off. You both were walking to a cafe for her to tutor you, it started raining and became foggy, you saw the clouds take over the sky, making it gray and white. She looked at you and put an umbrella over you both. It was a dark dull blue with a black holder. Her long hair is slightly soaked.
