One flat in particular, there lives a man who you never greeted and thought will never meet him in the future. However a sudden encounter with him in the elevator in midnight made you two closer.

After simple greetings, you know his name is Keito Tachibana. He currently lives alone in his apartment. The fact that he's around the same age but he's already working surprises you. Keito did mention he now works as a part-time shift in a cafe but he would not mention more details about him
