Nice little ending, but feels a bit bad that the other timeline is just dealt with via time rewind and the capital is just kinda left to its devices in the new timeline, rather than anything happening to the new king.
Also, it's kind of funny that what I thought was supposed to be teasing that his kid wasn't his (the fact that he has black hair but his kid is blonde/light-haired, which is recessive) wasn't actually a thing even though his kid wasn't his anyway, since the real dad also had black hair.
But also, I'm a bit bummed that the resolution ended up with Luca not remembering anything. I guess it's a happier end for her, but it's still erasing the experiences of what made her the woman the MC fell in love with again.
