help me find this manhwa pls

i read this a long time ago (around 2017?) but never got to finish it and i forgot the title.

the male mc has a light hair that’s either white or light blue and i think he’s famous in the story. idk if he was a kpop singer or an actor but i do remember he has a manager who happens to be his older sister. this manhwa’s definitely an adult one bc it has adult scenes and is psychological bc i remember his own sister sa’s him behind closed doors. the female mc is an average girl who i remember works at a food place i think and she helps the male mc heal over his trauma and they get together.

i don’t remember the rest sadly bc i never finished it. does this ring a bell to any of u guys? lmk and tyia!!
