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!
