There are some romantic subplots for several characters (mostly of tragic\unrequited kind), but romance is definitely not the main focus here.

They have a "we could've been in love, if we weren't so messed up" kind of relationship in the novel.

In the book she died in the end, but I doubt that the drama ending will be the same. They changed quite a lot of things in the drama, not to mention that it had already finished filming by the time the novel was completed.

The producers of the drama call it xuanxia. Basically, a mix of xuanxuan (fantasy) and wuxia.

Not really. There is also some mind control involved 😅.
This story is a lot. Like, A LOT. But long story short, they both have very legitimate reason to behave like they do, and it's not yet another case of "if only they bothered to talk it out at least once."

The senior brother was dying from a heart condition, so Tang Lici decided that taking out his heart and putting it inside himself to regenerate was a stellar idea.

Tang Lici actually wanted to save him. If you want further spoilers, see the comment below.

Well, it's not exactly a misunderstanding, sinceTang Lici did (technically) kill him 😅

He will be entering the main team soon-ish.

It's region locked on IQIYI - available for the US and quite a few other countries. Unavailable for EU.

ML's friend thinks Tang Lici killed their senior brother.

It will be revealed (probably soon enough). But if you want spoilers, feel free to see in the comment below.

During the early announcements, the name Lin Conghe was mentioned, but it disappeared from the official listings later on. I guess, we'll see tomorrow.

No, the novel is pretty obscure, and they changed it a lot during the adaptation.

No, it's just that the screenwriter seems to be new and hadn't been added to MDL yet. Teng Ping hadn't been involved in writing the script.

Her father in the drama is different from the one in the novel.

That outlet made it up. S3 hadn't been filmed yet, there only had been announcement (in 2023) that IQIYI plans to produce it.
