After three long months away from her daughter, Ayako is finally back home from her business trip to Tokyo, and she's brought back a big surprise: she's pregnant! It's only been a few months since Takumi and Ayako started dating, but the excitement of living under one roof ended up getting the best of them, so they accidentally skipped a few steps and took this giant leap forward. Now that there's a baby involved, things are going to get much more complicated... Will Ayako be able to manage the challenges of first-time pregnancy alongside her career? And Takumi may be a great support for her, but he's right about to graduate and begin dedicating himself to job hunting—will caring for Ayako and preparing for fatherhood all the while stretch him past his limits?
