Don't Toy With Me, Miss Nagatoro

An anime adaptation by Telecom Animation Film and directed by Hirokazu Hanai that premiered in April 11, 2021 and ran for 12 episodes until June 27, 2021.

Plot
When an introverted male student meets a girl called Nagatoro, his life is turned upside down. She first quietly observes his reaction to verbal abuse from some other high-school girls that are not well-meaning, realizes that oddly enough in his case it may be exactly what he needs, and so begins a sequence of her teasing him. It soon becomes increasingly obvious (to the reader, not to him) that her teasing is actually sardonic, well-intentioned, and flirtatious, but he eventually starts to catch on.
