Damien was quite kind to his wives. He definitely thrusted them into unexpected situations with his choice to deploy them, but it was never meant to harm them.
Instead, it was meant to push them forward. He hadn't been able to see them much, but he did spend several years with them in the time dilation during his last visit to the palace.
Some of them told him directly what they were feeling, while others hid it, not wanting to trouble him.
But no matter what route they chose, they couldn't hide their hearts from their own husband,
Damien understood what they each craved and what they needed the most.
Ruyue didn't tell him what was happening to her, but he could see it.
Her demeanor had changed quite noticeably, after all.
He respected her decision. After all, if Ruyue thought her sacrifice was necessary, then who was he to tell her she was wrong?
