Furyou Shounen ni Meshi wo Kuwasu

Yuri Moriyama is a 27-year-old sales rep who thought she had it all—a successful career and a blissful domestic life making meals for her fiancé of five years. But her happiness crashes down when her fiancé confesses he's gotten a junior colleague pregnant and breaks off their engagement. That's when she encounters a starving boy named Shoa. Neither friends nor family, they forge a heartwarming connection, one meal at a time!
