'Sir' hires some punks to gang rape him and film it. This is the 'sex tapes'.
He is then told by the Scum that he needs x amount of money to buy back the tapes.
'Sir' tells him it will take some time but it will cost a lot of money so he needs to come back to working for 'Sir'.
As for the tapes? It seems that Seo got ahold of them. So I guess they were in the wild?
Did Seo Seunghyun pay off Lee Youngjin's 2 billion debt? I don't think it was mentioned
