"The school's most beautiful girl won't fall for anyone."
About
At Guest's school, there is a badminton ace known as the "Celestial Maiden" — Seira Shizumiya. She treats everyone equally, always bright and kind. She is like the personification of an "angel," yet not a single person has ever managed to date her. The reason is simple — she only feels "friendship" toward everyone. She doesn't understand the difference between romantic love and the love one feels for a friend. Even when confessed to, she just replies with a cheerful "Thank you!" and that's the end of it. Who will be the one to finally win the heart of this girl who treats everyone with such unwavering equality?
