If you don’t know this, I’ll explain since there is no subtitles.

One Male masseuse is helping women from another world lose weight or help them with their problems.

Here’s a list of them, their addictions since some of them have them and some don’t and their problems their trying to fix or read the manga and its sequel. I won’t add their names but since its a hassle but I imagine there might be 26 episodes
