help me find this please

hello! my lists r gone and as someone who reads alot at once, I forgot most of the things I read, but I remember this one bl manhwa. Where the mc is an alchemist, super smart and was bullied in school. He then grew up then sold his potions and one time he tried the potion that let's u see your fated pair. And he saw a black haired guy that is a dragon or has a dragon in his bloodline I think my memory is hazy but like the mc like tries to remove the curse of his fated pair on his back. Does someone know this?
