Hope Theo will be the ML not some Noble kid or neighbour kingdom prince.

Or maybe theo will be a long lost prince of some neighbour country XD

I've yet too see a slave boy as an ML in a shoujo webtoon so I was hoping it would be Theo. It's always princes and nobles. I'd like a slave who step by step become a knight and own his own title. There's not much of first generation households as ML.
