Karou, the twin brother of super-model Tsubaki, is disenchanted with his own face, which bears a striking resemblance to her. This has led him to develop a distaste for men who are drawn to him due to his feminine features. However, his aversion is complicated by the attention of Shino, the president of a company that provides financial backing to Tsubaki's cosmetic firm. Despite being similar to the men who seek out Tsubaki, Karou finds himself conflicted by Shino's affections, questioning whether they are simply a substitute for his sister.
