trying to find this one BL manga

ok so i need to prove a point and i cant find this one BL manga i read like idk a year back. the cover of it was just a plain red background with the seme on the cover. he had like white hair, while the uke has black hair. seme is a "player" and basically gets w uke (uke confesses first cuz he thought seme was cool) and tells uke not to be jealous of the things hes finna do and yadayadayada seme ends up falling in love and boom happy ending. its set in a school/college setting. thank u in advance!!!!
