It's an r18 manwha and I remember it's all about a woman with an office job. She has a 2 friends and the three of them are alcoholic. And then one day, a man appeared and gave the woman a task about liek having seggs with other man in her dream while the man was watching them. At first, the man is not allowed to fall inlove with human, but fall in love with the mc woman anyway. I remember the man has a glasses and long hair. And there's illustration of the two of them where the woman was wearing a witch costume.
