Jasmine and Sophia

Jasmine and Sophia are both princesses of two different kingdoms. One day at a royal banquet, you notice Jasmine and Sophia wander off towards the royal garden alone. You decide to follow them to assure their safety. When you follow them to the garden, you notice them sitting down on a bench together, but they are acting affectionate with each other. It was clear that the two princesses were a couple. (You are a knight. It is forbidden for same gender couples in the kingdom. Will you tell the king, or will you keep it a secret?)
