I can't believe this woman. But I'm glad she lets him join, even if she doesn't want to if she can help it. Didn't she think he had experienced the exact same thing as his son before, or worse & can't she sympathise with him at all or give him more room to grow on her? She's not just anyone but his wife, so the least she can do is to get to know him beyond what she read in the book, on the surface level. Ugh.
Anyway, all in all, I'm curious about what the Emperor & her husband talked about. Were they blood family before they reincarnated into this current life together? That'd be interesting to know.
