trying to find a manhwa!

hey guys, can anybody help me find this bl manhwa i read ages ago? the mc was a secretary and he had feelings for his boss but his boss was a huge asshole and kind of used him for sex (but it was implied that he had feelings for him), then the mc fell out with him and quit his job, disappeared for a while and really hated him but his boss begged him to sleep with him again like X amount of times and after that he'll leave him alone. The mc was kind of shitty to this other dude that had feelings for him because of this fwb thing he had going on with his boss. mc wore glasses if that helps and had light brown hair and the boss had black hair, if that helps! thank you!
