His mind was not in the right place at the day he had a one night stand with Director Yoon. So even when he heard that in the beginning, he remembered that info later when Director Yoon talked about it. But when asked if he ever bottomed, he barely even remembered and said no, and then corrected himself after deep thought. But he prob cant remember the details of that night since he was just broken mentally and physically.
At least that how I see it and can make sense of it ٩(๑❛ᴗ❛๑)۶
One thing that feels off is that Yoohan knew about "Director Yoon" looking for the "Rabbit" that threw money at him 5 years ago, so why did it take him this long to realize the "dude from 5 years ago??"
