The proud sons of the three major families should have been each other's most evenly matched opponents, but they accidentally moved their hearts that they shouldn't have. One is cold and reserved, the other is unruly, they are supposed to be a perfect match. However, fate has already written cruel rules: there will never be any marriage between the three major families.
Intent: In the face of the iron law of class solidification, even a love that is evenly matched will eventually lose to the weight of secular rules and reality.
