trying to find this manga/manhwa im not even sure but it was black and white. mc breaks up with his gf, becomes homeless then ml takes him in. mc thinks he's straight so he finds ml's attraction to him uncomfortable at first. also ml is rich and is a fashion designer/ brand owner and mc starts working for him and they fall in love
