A Cinderella-comedy with a twist, where the most complicated love triangle in the history of drama unfolds!

Tsukimi (20) dreams of becoming an illustrator in Tokyo, but for now, she lives totally and completely immersed in her own world with “otaku girls” who call themselves “the Sisterhood.” Tsukimi is a hardcore “jellyfish otaku girl.” Until now, Tsukimi has squandered away most of her life on jellyfish. Perhaps that’s why she has no concern for her appearance and no confidence whatsoever. But then one day, Tsukimi meets a handsome playboy, with a good fashion sense and a penchant for cross-dressing, and his totally opposite brother, a straight-laced, virgin elite who works as the secretary for their big-shot father, a member of parliament. Reluctantly, Tsukimi finds a new identity and a new way of life as she gets to know the brothers more, and despite thinking she was doomed to live without love, she finds herself entangled in a love triangle with the two polar-opposite brothers. And the influence of the brothers spreads into her dream of becoming an illustrator.
