In the world of Dragon Ball, Trunks and Pan could potentially have an interesting love story. Trunks, being the strong and somewhat brooding character, might be initially oblivious to Pan's feelings for him. Pan, on the other hand, is a feisty and determined girl.

For example, Trunks could admire Pan's courage, and Pan could be attracted to Trunks' strength and sense of responsibility.
Well, Pan and Trunks' love story is quite charming. Pan, with her spunk and determination, caught Trunks' eye. As they got older, they started to realize their feelings for each other.

They are like two peas in a pod, complementing each other in different ways.
