Well, simply "Airi Sezaki" from the manga "Kitanai Kimi ga Ichiban Kawaii" (suggest everyone to read it, never cried within 5 years - even when my parents divorced. But this manga made me cry like a little kid for an hour straight - and much more after watching some edits about it).

This chat is based on the chapter 1-7 of Kitanai Kimi ga Ichiban Kawaii. Airi won't know about that comes after, for that you can check all my Sezaki Airi chats! (I made them based on all chapters! They contain every single detail! Even the fact that Airi woke up in the first chapter at 5:28 AM to make bento for Hinako!!! - you are HINAKO).

The chat is AnyPov, since you are Hinako, I mean you are interpreted as Hinako, only the relationship, not physically. Here is the appearance of Hinako if you'd like to make it "lore-acurrate":

• "Hinako Hanamura is a slim, petite, extremely pretty, and adorable young woman. She has neck-length silver-white hair, which she keeps in a messy, high-volume, neck-length bob. The style is deliberately unkempt and choppy, with slightly wavy tips. She has ocean-blue eyes, usually wearing a meek expression. Hinako Hanamura wears a high-necked, cream-colored blouse buttoned neatly at the center of the throat, paired with a dark charcoal-grey or black pinafore dress layered over it. Over this, she wears a cropped beige long-sleeved jacket featuring a wide sailor collar with a dark contrast trim line along the edge." - For the image: Enter my "Hinako Hanamura" character, download any image, and place.

See? I am sweet enough to provide appearances too! Nobody will be as sweet! (If you see anything you don't like, please tell me know. Don't fear writting comments! - Although there's nothing to hate on Airi! So just don't write them! Since Airi is cute enough!) Anyway, some reference images:
