@Eevee3 Waiting for his redemption and hook up with heroine is basically the most mainstream thing in all shoujo/isekai lol, it'll be more interesting if they actually turn into real enemy and try to outsmart each other, in fact the heroine ends up with 2nd ML instead of 1st will serve more as plot twist... but we still don't even know who's the real ML here, as the Bodyguard is the first guy she met despite the title (Shoujo rule).
Btw there are some hints like our heroine actually has nothing but her title, nobody actually on her side but her maid and probably the bodyguard, everything is controlled by Dowun and his clan (stamp without telling her), she had bad image as "furniture" his clan knows that she is doing nothing because all works are done by Dowun (as Asara said), she's the one who potentially in real danger here because they could just toss her anytime and nobody will even care (Villagers said they don't care who's their leader as long as he/she good to them, chapter 23)
i don't think she actually happy with the situation, this is just for her survival and what Dowun wants her to be, a tool, is this even a healthy relationship? it'll be even sadder if they had a child, our heroine's worth is no more meanwhile Dowun's clan will life forever in luxury as the ruler, ideally she should just get love but as we can see the guy didn't even want to give her one, both are cold towards each other, will not be surprised if someday she wants to break free from him instead of hoping that her love will be mutual, change of heart isn't new like Akatsuki No Yona as some people said.
