It's a pretty light-hearted isekai, the OL female lead is transported to another world, and to earn a living, she must cook lunchboxes. She meets some important figures in the palace and learns that she is capable of magic. Everyone is now trying to figure out who summoned her in the first place. I'm sure the romance will be between her and the wizard, but it's progressing slowly so far, and I like it. The female lead is a little ditzy and super cheerful, but she's not annoying to me, like some other similar female leads are.
