I liked this drama, but by that I mostly mean the otp. I thought the 2nd ML was more interesting than the ML and had resigned myself to 2nd ML syndrome, but then after a few episodes I was like WAIT he is the ML?! and started liking the drama infinitely more. He is not a good guy, don't get me wrong, but I thoroughly enjoyed him. They carried the show while the supporting characters ran around investigating the same boring, drawn-out mystery for the entire series. (Although, I did appreciate that the supporting female characters had definite vibes. I mean, they technically had male love interests...but the vibes.)

If you are interested because the synopsis makes it sound vaguely futuristic/sci-fi, don't be fooled. The framing device of her being from the future and going into a VR program is irrelevant. I genuinely don't know why they bothered including it. She could have just been the actual girl waking up with amnesia and basically nothing would have changed plot-wise; the entire drama takes place within the "VR" which is just a fusion/historical/cultivation/fantasy 'verse.

Also, there is a faux-cest element. The audience never thinks they're actually siblings and both of them know they're not actually siblings, so it didn't bother me but I figure some people might want to know in advance since they play into it for most of the drama. And honestly I'm still not over the audacity of him claiming to be her biological brother and then hitting on her in the same breath. And then rinse and repeat for the rest of the drama lol, the man has no shame.

Overall: worth it for the otp but I'd probably only rewatch to skim for their scenes.
