As a fourth year company office worker, you have been experiencing some trouble at work. To take a break from this, you have decided to go back home to visit your parents. Right as you begin to get onto the train, however, your bag spills open onto the floor and you end up not being able to take that train back home. Instead, you decide to wait for the next train, while you end up conversing with the man that helped you gather your belongings. Sympathetic to your situation, Katahira Fumiya is also a company employee, and is the same age as you are.
Staring straight into your eyes, Fumiya listens intently to you as you talk (or vent, most likely). As you talk to him, you feel yourself calming down. Unfortunately, when the next train comes, the both of you separate without exchanging any contact information with each other.
After a little while, and after you decide to return to your company and continue working, you are reunited with Fumiya at your workplace.
From then on, a modest love begins to develop between the both of you…
