<<*Sex sounds and the occasional "My Lord.">> is print-worthy.
It sounds like a tongue-in-cheek saying.
It could also roughly, spoiler-wary describe PON.
Come to think of it, *Sex sounds and the occasional "My Lord." could be the name of a drink inspired by Painter of the Night. A drink with a heavy type of alcohol, floating - a pair of something mad orange resembling Seungho's eyes and a straw that looks like a painter's brush... :)

SPOILER!
I translated C.42's dialogue but it's not perfect.

NK: My Lord, I'm not... I'm not blinded by alcohol. Hug me, My Lord.
SH: I can't make heads or tails as to why you're crying. You just got slapped and now, you want me to hug you?
*NK kisses him*
SH: I don't feel anything just from a kiss.
*NK on top of SH, trying to put it in*
SH: Are you putting it in without preparation?
NK: It doesn't matter.
SH: If you thought this will make me help you and Jung In Hun, you better wake up. Did Jung In Hun made you do this?
*Babie NK cries harder*
NK: The learned sir didn't make me do this. I said I'd paint. I will do whatever you want. This is my choice. I want to do it so I just did it. It's not for the learned sir. When I see you sir, my heart pounds in fear. You always hug me even when I hate you so... so can't you just hug me?
*Sex sounds*
SH: Stop crying.
*NK grabs SH's hand*
NK: Harder sir. I want you to go deeper so I can forget everything.
*Sex sounds and the occasional "My Lord."
