what's the manga of students where a tall girl who wears a mask most of time secretly has a crush on her friend who is a delinquent boy also theyre already friends when the story starts i think (there's some panels where they drink vending machine coffee together and they both cant stand it)

been tryna find this manga for over two years now i lost it when i used a new account but i really enjoyed reading it. The girl is kinda tall and wears a black mask and i think she has sliver or atleast white hair if I remember it well. The vending machine part it the part I remember the most tho.
