Looking for a manhua/hwa

i can't remember much anymore because i read it a long time ago...it was about a short girl with wavy hair, blonde, i think,,,being the master of a butler. that butler is a guy with black hair and i think he is a robot? sorta? In their world, having a butler means status...and this butler is very passionate about serving the girl but she gives him the tsundere treatment.... that's all i can remember please, pleaaasee it's been in my head but i can't remember the details so i can't find it..
