I see some of the ratings on this add the comments and am glad I ignored them and watched the series. This is a CLASSIC exchange of power relationship. Nhai plays a perfect brat sub while Ai plays a total caregiver dom. If you don't understand exchange of power in the bdsm world, I suggest you look it up. There are many types of relationships. This is just one of them. Understanding will be key in enjoying this series on a deeper level. A brat is always going to brat....and a dom will ALWAYS leave his mark when that happens.
