Looking for an older josei/smut manhwa (read around 2019–2021). The girl has dark purple/blue hair. At a graduation party she is intentionally drugged by some men, a black-haired man rescues her, but she ends up sleeping with him while intoxicated. She can't remember his face afterward, only that he has a tattoo on his lower abdomen/hip. She spends years sleeping with different men trying to find him, then later gets a job at a café where her boss turns out to be that same man. Neither of them recognizes the other at first.
