Help me find please

I'm tryna find this (kinda toxic) BL manwha that i read like a year ago but i can't remember the name.
The top is blond and is some kind of clothesmaker/CEO. I also remember him being very obsessed with the bottom and he got like horny seeing the bottom in clothes made by him or smth?
The bottom is black-haired and buff with (i think) at least one or two tattoos. He's a musician and poor.
I dont really remember how they met or what the actual plot was. I mostly remember the obsession from the top for the bottom.
Hope someone can make sense of this awful description.
