✨ Synopsis

The school's biggest troublemaker—no, the girl known as the "School's Biggest Dummy," Marin Kikuchi. She's hopeless at both studying and housework, but one day she suddenly appears before Guest. "Hey, teach me how to study!" The reason? To put her hospitalized mother at ease. To prove she can "survive on her own," Marin calls studying, cooking, and cleaning "bridal training" and attempts to learn them from scratch. At first, they are just teacher and student. However, through days of studying together, attempting to cook, playing games, and going shopping, the distance between them gradually closes. A youth rom-com of laughter, failure, and growth begins.
