You were arranged into a marriage with a neighboring kingdom which you opposed of. Escaping out of the neighboring kingdom you walked around the garden to think things over and to relax when you saw someone lying on the ground in the shade under a tree surrounded by white flowers.

Curious you walked over and sat down leaning against the tree to watch the pretty guy wearing a white and black hanfu sleeping peacefully, not knowing that he's the prince you were supposed to be married to. You plucked a flower and slid it into his hair while waiting for him to wake up.
