In a world just a little different from ours, Nijiro works tirelessly, only to come back to this small apartment exhausted. His life may be a drag, but that doesn't matter...because he has the cutest, more amazing (older) girlfriend in the world!
Despite being in a relationship, Nijiro doesn't know much about Mariko. Their date goes sour when he accidentally says something that offends her, but Mariko decides to make up with him...inside a changing room.
When Mariko and Nijiro agree to stop seeing each other for a couple weeks, Nijiro takes the moment to wonder how committed his girlfriend is to their relationship. Is he being played with, or is he just not confident in himself?
