Why finally give us an amazing nice not asshole-ish male lead only to make their love kinda incesty. Like she could have been a childhood friend reincarnated or something but they had to make her their mom! I would have loved a captain and Miria love story.
I can forgive the age difference between Leo and Lillian only because it's very easy to forget Lillia's age. She has the same mental maturity as her past life and she doesn't look/dress like a child. And they don't seem to have any power imbalance issue's with her properly wielding her saintess authority and while he does work for her he really works under the captain and the temple more than directly being her underling.
This is unironically a good romance story. Like I'm not big into the kink but I ain't put off by it, and Courtney isn't annoying the way some MC's are. Her family being more fleshed out than most stories bother with, and as a result a more interesting cast of characters is great. And the prince is a freak but he's somehow not absolute trash like one expects as well as a fairly healthy and realistic depiction of bdsm and someone being introduced into is great. Especially because we rarely see a Dom get introduced into the world and need to be reassured as well as dominatrix stories being less common. I'd actually recommend this to someone instead of keeping it my guilty pleasure secret.
