Hyakujuu no Ou ni Tsugu!

Yuka rules her girls’ high school as its king, with her friends relying on her and the boys afraid of her. The school is a place where girls are free to speak their minds, and Yuka seems to have everything under control. That girl-centered paradise is suddenly disrupted by a thirty-year-old man. Dates take place at golf courses, and kisses taste of smoke, changing the world Yuka has known.
