First: I LOVE this series! The wait and the suspense is killing me! Nevertheless I keep on re-watching the episodes to shorten the wait and hopefully improve my Japanese (total novice here!).

Maybe I'm interpreting too much, maybe it is really obvious for everyone, but I think Taiga doesn't sleep with his clients, because he hasn't slept with anyone at all yet.

That's why he hesitated with Akina in the hotel. Fear of failure and maybe even more, something he doesn't want to be taken from him, something that is not for sale. 

Yes he says, in episode 4 that he would bend the rules for Manami, but I think that was just another test for Manami. Testing if she really doesn't have an ulterior motive.

Besides all that, I really hope for a happy ending for the two. Not sure how that could work, but I don't want a sad ending, where Taiga becomes the next victim of the host killer. 😪 

What do you think?
