please help me find this yaoi manga, I am really desperate, I can't sleep

a bl manga/manhwa where the main character is a famous actor very kind and caring and the other main character is a fresh graduate assistant of the director and treated poorly on the set, but they are in a secret relationship, I think their names are Hajoon and Seojun or maybe I am wrong about the names and mixed it up with another story so please just focus on the description, I forgot the title and I can't sleep thinking about it
