Season 1

Take Seiji quits his job after three months. With no dreams, no savings, and a poor relationship with his family, he becomes a hikikomori. However, after his mother falls ill with depression, he ends up taking on a part-time job at a construction site. Because of that, he soon decides to work towards rebuilding his life: "Even though I'm just a freeter, I'm going to buy a house for the sake of my family." One of the people he meets at the construction site is Chiba Manami, who graduated from a top university and joined a well-known general contracting firm. Manami is the complete opposite of Seiji, but while their personalities clash at first, they gradually come to understand each other.
