I Became a Maid in a TL Novel
In the OG novel our protagonist isekais into as an orphaned poison tester, she dies quite early on. As her isekai'd self, she lives on having gained the king's affection. I'm a little concerned about the age gap (I don't actually know what the gap is, but it seems quite significant), but it's pretty good regardless. Edit: the age gap makes me uncomfortable and the ML has a confinement problem. I dislike him. I like Ricardo, but for myself - our FL is, again, much younger than him. Oh, and when I mention age gap, I mean SHE'S 15, A MINOR. Yikes.
