Yuino says that five years have passed since she got married, and her marital life is no longer stimulating.Although she used to be busy, she used to celebrate anniversaries and go on trips, but it seems she hasn't done anything in the past few years.In addition, the lack of communication with her husband is serious, and she rarely eats together, let alone work at night, and recently her bedroom is separate.Perhaps because of her loneliness in her daily life, her cheating heart has sprouted in order to fill the gap in her heart.
