Ippai Tabete mo Ii desu yo

It's difficult to call the salaryman Izakura a "full-fledged" employee as he has a somewhat unusual fetish. Because of this, he finds it a bit challenging to dine with others. One day, by chance, he stumbles upon his boss, Asumi, a far cry from a connoisseur of B-class gourmet, devouring an extra-large bowl of ramen at a restaurant near the office! Witnessing his boss's voracious appetite, Izakura's fetish is triggered... Izakura, who wants to watch Asumi eat, and Asumi, the boss who loves to eat, find themselves in a situation where supply meets demand. This is a unique story of a subordinate with a peculiar fetish and a competent boss with an insatiable appetite, featuring a bond over meals in the world of BL!
