I know, I know, writing a review at the halfway mark without knowing what comes next is wrong. But the fact that they've already messed it up till here makes me want to write one. I will update this review if things change.
So, here's my impression of the first 24 episodes.

I feel like they really could've had it all but I think they got lost somewhere trying to balance the scales.
I have read the novel, and might be a bit biased but LSS doing all sorts of things to go against TTJ when all she had to do was talk seems a bit excessive.

The scene when TTJ sees LSS lose it, right before she teleports is probably the only things that's kept me glued to my seat. Because that spit second when TTJ goes all solemn when let's out that painful scream tells you that he knows the feeling of losing everything, of being pushed to the brink of hate. The only things is he found solace in the evil because it gave him power to protect himself. He probably would've offed himself only if so many attempts at his life hadn't already been made. Like we saw in that dream, he wasn't alive because he wanted to, but because others wanted him dead so he stubbornly persevered on and kept himself alive.

They made TTJ more human, and I truly appreciate them for this. Here we can see him understand the feeling of love and then get betrayed in the worst way possible and Yunxi is just *chef's kiss*

But then what happened to them when they adapted LSS? She started off amazingly well as someone who was on a mission, with all her pain and suffering and just trying to survive and save TTJ. But then how did she get dumber and dumber as the story progressed? She's confused in her feelings and wants the spikes to form ASAP so that this can end. BUT on the other end, she's secretly helping XL break out of prison, completely unnecessary might I add, that will effectively dissolve all the previously formed spikes and take her back to square one?

And pleading for and taking YBS home on the very day that she's about to drung TTJ? Like really sis? She betrayed her husband for her so-called survival, showed off her affections with TTJ while being married to XL, but one smile and good talk with her and it's all water under the bridge. Her logic being that if she had everything then she wouldn't have turned bad but then isn't that the case with TTJ too? She saw him being betrayed time and again and almost lose his life to the people that were supposed to protect him but nope, he's gonna turn bad the moment he takes a misstep.

I kinda liked the novel LSS more, where she's living this life like a third-party, existing because of her mission and only showing kindness to the ones that were good to her. She gave no f's to YBS and even found out about her evil intentions and while she did love TTJ, she wasn't constantly hot and cold with him. And TTJ saw that, which was why he was always looking for ways to bind her to him because he knew that if she wants, she can go away and never come back. That desperation pushed him to madness.

I will watch this to the end because my god was that opening incredible. And I'm kinda still rooting for them despite the u-turns that they've taken. And YunLu is love so no way I'll leave halfway through.
