After this second chapter, it confirms my fears. The Yuri was added at the last second. The story is going to focus on the prostitution industry, or rather "in-store health". It's not a bad thing, but it doesn't interest me. I don't care about straight men's prostitution works.
At worst, they should have talk about the problems in prostitution in Japon. At best, they could have talk about why there is no real lesbian prostitution in Japan. Most of the so-called lesbian prostitution are run by guys for guys.
The only thing that brought me to read this manga is the Yuri tag. And I think that the relationship between the MC and the top girl will not be romantic, but only admiration. The MC "She is beautiful", the top girl "She is cute".
