A short format drama with a plot that isn't overused! The ML is Zhen Zi Qi and they actually don't dub his voice, which is super growly and yummy! FL is Jia Yi Xuan a very adorable and popular short format actress.
A quick review without giving away too much. ML goes to an island that houses all the mentally ill of this society. The island has no laws and no keepers, except every resident has a bracelet for life so even if they escape somehow, they would be found out in normal society.

FL was thrown on the island once her adoptive parents no longer needed or wanted her, they adopted her to ward off evil for their natural daughter, when she grew up and wasn't needed anymore, they intended to sell her for "marriage" to an old slimey man but she fought back...hence she ended up on the island.

ML has some trauma from his "sister" who unalived herself in front of him many years ago after killing some people who abused ML and possibly her too. FL bears some resemblance to his sister, so that's why he picked her up from the island.

I don't think I've seen any other drama with a similar storyline, most of them reuse the same old plots a million times over. I liked this one for the story and for the leads. Some mild abuse in the beginning, much more mild than the sadomasochistic ones that are becoming all too common, but still not acceptable to ever put your hands around someone's throat. Other than that, a pretty decent drama and worth the watch.
