Promise To Marry Me When I'm Older!

childhood promises are often taken light-heartedly, but what happens if an innocent little girl mistakes a dismissive comment from her tender years as a commitment tor marriage? that's exactly what happens when yuka asks ryo to keep his promise to marry her — even though it was 10 years ago! but the kind-hearted ryo just can't find it in him to give it to her straight, and so ensues a wacky comedy of silly cover-ups and failed attempts to set the record straight!
