I don’t lose much if I don’t play this game, but if I play the game and receive inappropriate content, then I will feel uncomfortable (I am a rather susceptible immersive player). So I ask questions to save time and nerves.
I understand, and normally I would encourage that - I just mean that this game is rather different from the ones that you seem to be thinking of. It's like if you saw people talking about RPGs, only to find that they were talking about WRPGS when you'd only played JRPGs before. There's enough commonalities to talk, but the baseline expectations are different enough that it just leads to confusion.
You seem to be thinking of the typical VN, with long routes that have minimal variance, and an experience tightly crafted around a small cast of characters that puts a tight focus on the emotional reactions of the viewpoint characters. That's... Not really how this one is written.
Instead, most events go by triggers instead, with a high degree of random variance. Either as Rowan explores the kingdom (which usually provides events that have nothing at all to do with the Alexia or the other castle residents), at the end of each week (which have as large a chance to deal with castle management as it does with anyone else), or explicitly triggered by the player clicking on the name (which usually delve more deeply into Rowan's relationship with the castle residents - but which could just as readily be a growing friendship as it could a budding romance. Sex is highly present in the game, but you can be as chaste as you want without anyone but Jezera judging you.)
Eventually, Alexia will ask for a job, but... If you're so inclined, you can just stash her in the library to good effect, and nothing at all will happen to her. Well, okay, there's a pervy bookshelf, but she can just avoid touching it. The same is true of most jobs, actually - only putting her under Jezera's care will necessarily push her boundaries, and, well, that's to be expected, really.
And the overall plot itself... It really is focused on Rowan's efforts to build an army up from scraps, and conquer the kingdoms that the last demon lord failed to take at the height of his power. How this affects his relationship with Alexia is an important part of the game, but you can spend an hour with him scheming to take down Rastadel's defenses without Alexia ever coming up.
