Looking for a BL

hiiii does anyone know a Korean BL that goes along the lines of black haired rich seme is in love with uke but uke doesn’t return feelings into very later into the book? im pretty sure the seme doesn’t actually love the uke but instead a guy in his dream that looks like the uke. i think the uke dyed his hair blonde after trying to get over his feelings for the seme… also i think either the seme or uke self harmed pls lmk
