[Haikyuu!!] My Boyfriend Is a Libero

Tsukishima Natsuwa is Kei Tsukishima's older sister by seven minutes. She's a good-for-nothing at sports, a dummy at school, and not very nice either. Her everyday conversations with her older and younger brothers usually go like this: Tsukishima Akiteru: Come on, try again. I know you can do it. Kei Tsukishima: I think all your intelligence must have been given to me. Growing up squeezed between one brother's warmth and the other's chill, Tsukishima Natsuwa somehow made it to high school. But with puberty doing its work, her late rebellious phase suddenly took off, pushing her out of her comfort zone. Tsukishima Natsuwa: That's right, I'm in love. Kei Tsukishima: Who's the unlucky guy? Tsukishima Natsuwa: He's... a second-year senpai, someone whose name is something Nishitani. Tsukishima Akiteru: Is it really okay to start dating someone when you don't even remember his name? Kei Tsukishima: ...Wait, who did you say? Nishinoya Yu, who'd been caught in the middle of it, was very surprised by Kei Tsukishima's retelling. After following a long and winding train of thought, his answer was: "You don't approve?" Angsty teen romance heroine x cheerful, energetic ray of sunshine. Theme: Let passion heal the pain.
