Hmm that's an interesting take on it. Would the sensei have been so sad afterwards if he had just had sex with someone he liked? That's the only thing keeping me from agreeing with you completely.
Well maybe sensei was sad since he knows that the guy had sex with him purely out of fun and is not actually interested in him. Wishing for love?
that is what my assumption too. I agreed with you.
I think sensei is in love with shou instead of the prince (I forget his name). When he heard Shou said about his "favorite" part of that opera, he seemed please, like "woa, you and I share something in common, it's great", that feeling usually for your crush, right? And when they woke up after sex, sensei even played that part for Shou, so romantic and gentle act that imposible for someone who just got blackmailed and raped. And when sensei found out that it's not what Shou likes, he seemed disapointed, that means he doesn't give a damn for the prince, he only have eyes for Shou.
So, I think there will be a twisted plot here and sensei isn't all that innocent but quite a player (๑•ㅂ•)و✧
