Mayumi Nakai is 40 years old. It's been 21 years since she got married at the age of 18. At the time, shotgun weddings were still rare, and Mayumi was worried about whether to have children or not, but now that her child is a grown adult, she suddenly felt like she had reached a turning point in her life. "Even though it was the result of my youth, I think I've persevered through a lot and done well. Now that my child is older than I was back then, I hear him say things like, 'Marrying in your teens is impossible,' and it makes me want to cry... I think maybe I should have had a little more fun..." Today, we'll do our best to help Mayumi recapture her youth!!
