Two females are in a relationship. The couple is not an intrinsic lesbian, but they fell for each other by chance. Tokiko has trauma with her past fiancée and continues to sleep with several men as if she tests Haruka‘s love. In contrast, Haruka strongly believes the patience and tolerance against a partner‘s irrationality means the power of love. With the emergence of Satoru, a handsome young guy, their love of soul gradually transforms into a twisted codependent relationship and gets mad despite themselves.
