Help....

Hi, some time ago I read a yaoi manga, but I can’t remember the title. I was wondering if, since you seem familiar with this genre, you could help me out. The story is set in a medieval-like era, and the protagonist is a bottom with white hair and violet eyes, while the top is a blond king. If I’m not mistaken, the king met the boy when he was a child and saved him. Later, the boy is adopted by a noble family who sends him to work for the king (and during all this, he changes his name). Does this ring any bells? Sorry for the somewhat strange question, but I really wanted to keep reading it, and it’s frustrating not being able to find it anymore… In any case, thanks for reading my message.
