With a carefree outlook on life, Hiroto knows better than anyone that slowing down is sometimes the best way to move forward.

At 29 years old, carefree Hiroto Ikuta doesn't have a girlfriend, a full-time job, or a plan for the future-and he couldn't be happier. Hiroto's breezy attitude isn't easy for everyone to understand, though. In a world filled with anxiety, confusion, and grief, Hiroto and the people who surround him are all just doing their best to figure out this thing called life.

Christmas is right around the corner, but when Natsumi ends up hosting a holiday party, she runs into a bit more trouble than she bargained for! Meanwhile, Hiroto and Yomogi can't seem to stop running into each other. As the lives of this laid-back part-timer and serious realtor continue to collide, they may just find themselves becoming less and less set in their ways.
