A burnt-out chef finds himself running a boarding house with a woman who shouldn't exist, and somehow that's exactly the comfort food this show needs to be. The cast slides into each other like they've known each other for years, trading dialogue that lands because nobody's trying too hard to be funny. By the midpoint it starts chasing bigger sci-fi ideas and loses some of that cozy warmth, but the chemistry between Takumi and Mira carries you through anyway, warm and uncomplicated in a way most rom-coms forgot how to do.

Takumi is a talented chef who has just lost his job. He is offered work at Astro-sou, a run-down boarding house, but he wavers once he learns the position means living on the premises full-time. Meeting Mira Gotokuji, the lovely and charming landlady who adores his cooking, settles the matter, and he takes the breakfast chef job and moves into Room 5. As they work side by side, their bond grows. Takumi starts to notice odd things about Mira: she knows almost nothing about modern technology or Japanese food, and he hears an unfamiliar voice coming from her room. He has no idea that she is an alien, newly arrived from another planet on a secret mission. The series mixes romance, comedy and science fiction across its twelve episodes.
