Ii kara Damatte Kiss wo Shite

The Hinokami and Mizunagi families have been at odds with each other for many years, and there is an ironclad rule that they must never love anyone from the other side. Juri, the daughter of the Hinokami family, has made up her mind that she will marry the man of her parents' choice for the sake of her family. One day, Juri goes out and is suddenly kissed by a man. It turns out that man is a member of the Mizunagi clan… This is a modern version of Romeo and Juliet as depicted by Watanabe.
