I don't think he was trying rape him, he was asking which part of your body (I think he said indecent body) did you use to seduce Seungho while pulling off Nakyum's clothes. Also, it gets worse since he basically confessed in his last line that he's the one who ruined the painting and that Nakyum should've been half dead from the beating he was supposed to get, which Seungho heard.

I am seeing some of it now. Chapter 18 is probably gonna be Jihwa getting his ass whooped. He goes ballistic on the Painter. I don't know if he wanted to rape him or strangle him. But he loses it majorly. Yoon arrives in time and has the grin of "Boy, you don't know how much you just ***ed up".
