The Master was evil and the slave didn't receive another lash.
As contradictory it was, the singer was enjoying being treated like a slave. There was a little bit of pain, but the reward with unknown pleasures had won the singer over.
Haruki felt like reversing roles the next time, he wanted to be the Master the next time.
'WHAT?'
It wasn't a dream. He was definitely in the room with Saito. He was cheating on Jun!
Worse, he already admitted to himself that he would have a next time.
The singer had conflicting feelings, to like and hate what was happening. Especially now that he was fully aware of being real.
How to explain to Saito that he loved Jun, but wanted to make out with the man he just wanted to be friends with? Friends with benefits, as they said.
