The word for this is HOT... The two ML's are hot together, end of. If you are looking for something more abt this drama, like villains or conflict or anything - there is not much to it. It's just one - or even two! - gay couples that come up with hot stuff, and thats it! We have role-play, innuendo, teasing, flirting, naked bodies - and i mean, ripped bodies!, power struggle - you name it.
Oh and there is also some comedic relief to the sexual tension... I guess the director was afraid to handle the 18+ content in a mature way so he turned to this trick instead.
Rewatch? Why not? Its funny and... wink wink. Sex sells!
