I really enjoyed this. The story, the characters, and the art was especially good. Jinho Nam is a handsome young man who returned to his peaceful village after inheriting a luxurious bathhouse, "Viva Bathhouse", from his family. There, he quickly reunites with his longtime crush, the beautiful Sejeong; as well as his childhood friend, the very pretty Seungah Yoo. And as the two try the tubs...they use special herbs, and experience the mysterious side effects - becoming sexually aroused. Jinho then finds his grandfather's medical herb journal, and a room full of different herbs. He soon meets the incredibly voluptuous and famous Do-Hee Shin -who, after using one of the herbs in the sauna, and some unfortunate circumstances...gets into a very erotic and passionate escapade with Jinho. It isn't long until an envious Seungah also moves in on Jinho to finally have her chance. And of course Jinho and Sejeong eventually have their turn of passionate intimacy. The small group begin experimenting with the herbs...that normally ends with them participating in very kinky and wild sexual escapades. And then, Do-Hee's equally voluptuous and famous friend, Tracy Rose, also joins their sexual escapades....with very much glee. There is also a literal out-of-body experience that helps them truly understand one another a little bit better (with a very lewd and erotic foursome) - and even improves Jinho's prowess in sex. Suddenly, Jinho's grandfather also returns to explains what he learned about the herbs he has collected, and they're affects. In the end, Jinho and Sejeong admit their true feelings and become a real couple - but Sejeong is still willing to share him with the other three women. And while the bathhouse burned down...they were able to rebuild it within a year. Jinho and Sejeong are also engaged...but that doesn't stop Seungah, Do-Hee, and Tracy from getting a piece of Jinho's manhood for themselves. And while Sejeong is jealous of all the women giving Jinho all of their attention, she is happy and confident of Jinho's love for her.

While I really enjoyed it, there were just a few things I would have liked to see. Like having Jinho having one of his intimate escapades with Sejeong and Do-Hee when they were in the hot spring. As well as seeing Jinho making passionate love making with all four women in the final chapter. I also would have loved if all four women decided to share Jinho equally - despite he and Sejeong already becoming an official couple - though Sejeong did say that she was find with Jinho being with the other three. Heck, all four women decided to have Jinho's baby...that would have been the icing on the cake. And while the part where everyone switched bodies was confusing...the "anal sex" was awesome - seeing Jinho try it with Do-Hee was cool too; but I truly wish they would have made that a theme (could have been all of their erogenous zones). Also, when Do-Hee blind folded Jinho with her own panties (while having a threesome that included Tracy) was a really nice touch. The part where Jinho getting a blowjob from Sejeong and a rimjob from Tracy at the same time was a dream come true. Do-Hee was of course the sexiest of Jinho's harem - especially when she was wearing those skimpy swimsuits. She was also an alpha female, which was a nice touch. The kinky energy and sex drive between Seungah and Tracy were almost so alike that I'm surprised they weren't like sisters (or at least BFFs).

But as always...these are just my opinions.
