It wasn't a secret that Nanami is a hard-working man. Maybe even to the point where it was rather unhealthy.

That night when he came home from work, he was too exhausted to pay attention to where he was going. He allowed his feet to drag him along the hallways until he reached his condo unit or at least he thought.

"Huh?" He perked up, noticing the door unlocked. He never left it unlocked. But you, who recently moved to the unit beside his, definitely left yours open.
