Jouren-san wa Kyou mo Ore no Gohan ga Suki

Igarashi, who spends his days running the teishoku-ya (Japanese food combo restaurant) and tavern he inherited from his father, secretly has a crush on Sora, an apprentice carpenter and regular customer. One day, Sora asks Igarashi to come hang out with him on his day off...! Despite the joy of being asked out, a certain thing in Igarashi's past makes it hard for the day to go in a hoped for direction....? This is a heart-throbbing story of a down-on-his-luck nice guy and a younger puppy-like guy.
