bloodhound?
Your description kind of reminds me of https://www.mangago.me/read-manga/frey_drac/ but that's a manhwa, not a manhua.
Yes this is the one! Sorry for the confusion
Can someone help me find a manhua where the blond top was finding his younger sister with the held of the black haired bottom?? The bottom also hired him as a bodyguard ig?
