Give the crown prince some slack, if he showed that he cared in the first life, she would be killed and then be replaced by Veronica. He had to be like that so that it'll buy him some time to actually gain power since the dukedom was pretty much more powerful and influencial than the royal family.To them, he was only a puppet. He had to keep everything under wraps so he could uprise against the dukedom who was pretty much using the royal family for their own benefit. He thought he had enough time to save her but sadly he didn't. It's not like remarried empress were the crown prince was an actual trash. And also, don't forget about his child, he knew that the child would die because it wasn't Veronica's and the child was just colateral damage to Veronica and the duke, he had to find a way to save the both of them.
