In the back alley beside the building of a major publishing company, a cafe quietly stands. Ryouhei, a gay man who's also the cafe's manager, and Ookura, his ex-classmate who's now an editor, have been in a relationship that had started from a fruitless unrequited love.

One day, Ookura asked Ryouhei to marry him but Ryouhei found himself unable to say yes as he feels guilty towards Ookura who was initially straight.

At the same time, he learned that his father got hurt and he took the chance to take time off work to return to their hometown but...?

This is the decade-long love of a cowardly man who is still afraid despite being loved.
