Asahi runs a small bento shop that has been in his family for generations. One day, a new customer appears - he's really out of it, especially after seeing Asahi for the first time, but after that he becomes a regular and Asahi somehow cannot stop caring about him...
This was very cute, but it would have been even better if the seme had been a normal salary man rather than an otaku and successful mangaka. And god, I want to read the story about Asahi's elder brother!
