With all the wishy-washy stuff with the "love triangle" between Shio, Ran, and Gai... this could have been easily pulled off volumes ago ._. (and it would have been a shorter series and WAY less dreadful). Because, tbh, it's more interesting than what is going on between them and their love triangle.
It follows more or less on the same sense of danger that I had at the start - if you didn't know what you were going to get into (or you were quite skeptical), you would definitely be thinking this was only a disguise for as a sexual business when it actually is not (the guys betraying their own rules aside, i.e. Linda).
Also, really... Yumi, wow. Just wow. I don't trust her now. And I don't think Gai is going to change her opinion based on facts, either :/c
