Of course, Roy's depression only lasted for a bit before he felt relieved.
Age had never been a problem for long-lived species. Julia was more than two thousand years older than him. Wasn't this fine? He would get used to it.
Moreover, Roy knew that Lilith didn't have any ethical concepts. She wasn't human and could do whatever she wanted, so he naturally couldn't ask her to follow his own way of thinking.

Although they had not signed any contracts for this transaction, both parties tacitly followed the rules of transactions. She had already obtained what she wanted, and now it was his turn.
