Food manga about Ryota, a university student, who ends up harboring Yakuza boss Ryuichi in his apartment, who ends up cooking delicious meals with leftovers.
The twist that a criminal is actually a good chef is entertaining and there’s a good amount of comedy with Ryota trying to hide the fact that he has criminals staying at his place. It’s based on a novel and there’s also a live-action TV show as well.
