Sukina Ko no Shinyuu ni Hisoka ni Semarareteiru

A character repeatedly expresses affection for Misa Yosaki, who is described as strong, proud, and especially cute when smiling, but is always turned down. Haru Hinata, Yosaki's best friend, frequently interferes. Yosaki appears to enjoy watching the two argue. Their routine is disrupted by an invitation that changes things: Hinata offers herself as a substitute for Misa, suggesting the protagonist can do anything with her. The situation becomes more intense as Hinata, once just a friend, makes a passionate request while showing emotional and physical vulnerability.
