I read this manwha about two times already. It's a cute and harm felt. I think I also enjoyed the angst between Athy and Claude. It showed the development of their relationship and how Athy was a step closer in reigning as heir to the Crown.
Although, I hated that Claude hated Athy cuz she "killed her mother" = no valid reason at all. So yeah, and I found the forgiveness a little too fast, but ig I just enjoy angst too much.
I'll rate it a 8-9/10. I loved the angst at the beginning so I'll give that a bonus point igggg
