Yanagi Kenta had quit his job with a big chemical firm, to succeed the family's laundry business 3 years ago. At that time, he had divorced his wife, Saeko too. Being clueless on how to deal with the customers that walk through the door, Kenta leaves it to the family's long serving employee, Yan, to run the shop. One day, he receives an invitation to the class reunion for the 34th batch students of Tachisakashita Middle High School, his alma mater 25 years ago. The invite brings to Kenta's mind, memories of Akehi, the girl with whom he had been going out for a few months at that time.
Akehi is now married to a famous hairstylist, Taro, with whom she has 3 children. On the surface, it looks like a happy and ideal marriage, but in actual fact, Taro is a temperamental man who makes Akehi feel really small with his cutting words.
Sakurai Ryosuke was the popular guy back at school. He too is married, but he feels suffocated in his marriage and wishes to find true love.
Hirono Kaoruko is a successful pharmacist, who dislikes playboys like Ryosuke. Having been hurt by men in the past, she shuns marriage and focuses on her career.
The four of them are reunited at the class reunion. Kenta and Akehi; Ryosuke and Kaoruko. Two couples in pursuit of true love, but at 40 years old, time is not on their side. Yet, it is still not too late to start all over again...
