Read thru chapter 25.2. Adults I think. They're both probably 20 or so. Mc is a poor hardworking orphan, and he gets drunk one night at a party and wakes up in a hotel room. He leaves a note and sneaks away to work, but then he's absconded by some MiB. Turns out he was with the secretive crown prince last night. This story is very cliche and very shoujo-esque. Unlikely circumstances put some peasant in the path of the biggest catch in the land, and the biggest catch just happens to like them for SOME REASON. Then the mc keeps doing "normal" stuff that draws the prince's interest since his life isn't normal. I don't like the art much and it's hard to take any of this seriously when it leans so heavy on shoujo formulas of yesteryear. This is complete at 60 chapters on lezhin, but I don't like it enough to upload any. Also chapter 23 is badly in need of being reuploaded in a sensible order. Honestly I'm glad that it isn't complete here because I didn't know it's actually 60 chapters and am not really interesting in reading that many chapters of really bad shoujo tropes.
Your Highness, Please!
