For Takumi Mitsuda (Asaka Yoshihiro), who has always been single, the diversified marriage model has nothing to do with him.On the other hand, Takuzo's ex-girlfriend Mia Yanoguchi (Aki Asakura) feels very anxious every time he sees his friend enter the marriage hall and thinks he must get married too.
In response to this, Miai's current boyfriend and dancer Shinhei Saimura (Suzuki Okawa) casually ignored her hint of wanting to get married.It’s not that Xinping doesn’t want to get married, but because he knows his personality well and thinks he is not suitable for getting married.However, Shinhei made an unexpected suggestion to Miai - if three people are together, they can get married.
Meiai is unable to accept Xinping's proposal and is very worried.One day, Miai learned that the rabbit they raised together had passed away when they were dating, so she took Shinhei to find Takuzo.I originally thought this would arouse Takuzo's jealousy, but I didn't expect Takuzo and Shinhei to accidentally get along...!?
