Oh no no. So basically ml is well known as a dokaebbi who sleeps around BEFORE he met the love of his life eunyong(happens in "joseon era"). So ever since he met eunyong, he never slept with anyone else especially after he died. He was just so heartbroken and kept looking for the reincarnation of eunyong, in that period he never slept with anyone UNTIL he met geunyong cause he looks exactly as like the mc in the joseon era
The only thing mentioned/hinted in the manhwa was the ml has been in a relationship other people(not mentioned in the manhwa if he has slept with them), but the relationships were described to be pitiful because in the end those people were actually pretending to be the reincarnation of the mc just to take advantage of him, leaving the ml to be betrayed and heartbroken each time. Thats how its described and understood from the manhwa

Hey I haven't read fully .Are both ml and mc are sluts ? And the did the ml also slept with I don't know how much people for thousands of years ? Atleast mc should be massive slut so ican give it a try
