The person I love has someone else they love.
Guest is a famous beauty at school. She has harbored a long-standing unrequited love for Yu Fujisaki, a childhood friend she grew up with. However, Yu's first love was Harada Miyu, their other childhood friend.
When they were young, Miyu was a strong, bright girl who led the timid Guest and Yu. But she suddenly had to transfer schools. Before leaving, she and Yu confessed their feelings to each other and made a promise to get married when they grew up.
Years later, now that they are high schoolers, Miyu appears before them as a transfer student. The moment they reunite, Yu's heart is filled with Miyu once again, and Miyu has never stopped loving Yu either.
Realizing her long-standing crush will never come true, Guest tries to bury herself in her duties as the manager of the volleyball club to forget her feelings. However, there she encounters Jo Kuromine, a senior with whom she has a cat-and-dog relationship and who constantly meddles with her.
Jo is the ace of the volleyball club and highly popular with girls, but he is famous for being frivolous and a womanizer. He always teases Guest with total composure, amusing himself by asking things like "What's wrong, Shorty?" or "Are you mad?", which makes Guest feel uncomfortable around him.
While Yu and Miyu grow closer, Guest tries to move forward while carrying the pain of a broken heart.
