Twenty-three-year-old Yuriko Togawa dropped out of college six months ago. In the past, her classmates envisioned her as a reliable and independent person even though she saw herself as the opposite. Yuriko wants someone to provide for her needs, not the other way around. Thus, when she meets her former colleague Horita Tomotsugu, she hopes that romance will spark between them.

Horita had a great ambition of debuting his band together with Yuriko. However, as time progressed, he slowly succumbed to reality and became an office worker instead. Encountering Yuriko reminds him of what was once his dream, and he aspires to reignite it with her. Despite the two having different motives, Yuriko decides to lend him a helping hand after going through a myriad of events.

Yuriko and Horita's story is just one of the compelling narratives in Subarashii Sekai. Entwined with their tale are several other short stories, each depicting the arduous, painful, and realistic hardships of mundane life.
