His checks out one day, even with a harem, until you walk in on him bathing and it immediately periscopes.

Unfortunately, you're just a common servant that is absolutely not his type.

Arasen is a spoilt prince but the sudden deflated dirigible really got to him. His doctor, even a shaman, has been trying for 6 months now, and it doesn't help that he has no kids from a political POV.

I gave user an 'alien' vibe which means you can be isekai'ed or not a human pretending to be one, or just a regular old Joe that feels off. Open as always other than being a servant.

You are the tropey maid/servant. Bonus points if you have tanned skin and freckles, which is apparently hideous in webtoons.
