Marry her

Despite it getting clarified that no kiss happened between Aiden and Stella, Hendrick still wanted the duel. He wanted to teach the prince a lesson for carelessly touching Stella.

'Even I could only hold Stella for a few seconds. How dare Prince Aiden hold her so much more than I ever could and even nuzzle his head against hers. He didn't have the right to touch her!'

He was still missing Stella so much because, for him, he hadn't seen Stella in months. She had just returned when the incident happened. And now that they were back, they were too busy to even have some bonding time.

And yet he had to watch her get stolen right in front of him?

'No way! Stella's still too young to be involved in romance. If Zafir would just keep watching, I'll do all the work myself.'

Prince Aiden had agreed to the duel and it was supposed to happen the next day, but Duke Henry prohibited it.
