I like this so far, but I do find it a bit unfortunate that it's already missing some small details that helped with the future character development.
In the novel, when the FL asked, the system stated that the author of the novel she has been given a second chance in had made a point of foreshadowing the character's futures with seemingly pointless inclusions in the descriptions. Such as the FL suddenly feeling ill and the described headaches and throes of dizziness as a hint towards her later terminal illness. The author hadn't wanted it to be "out of nowhere." which it seems is what this manhua is doing despite that.
In the novel for this adaptation, when the FL enters the classroom for the first time, she is suddenly dizzy and questions the system if that was due to her later diagnosis. (It is.) The reason she so obviously sniffs the ML (here) is that his scent which is slightly medicinal helped calm the aches and pain. Which leads to another detail that this adaptation has left out, why the ML smells medicinal. It may be mentioned later, so I won't going into too much detail, but he often takes vitamins for his insomnia. In the scene when she sits down at her desk for the first time, he wakes up and the first thing he does before even recognizing her is taking a few vitamins.
It's small details but by chapter 30 in the novel and the ML's back story is revealed, you realize why they were included.
Again, I just find it a bit unfortunate, but I will continue to read this as it's a cute story and definitely worth it.
The FL is endearing and steadfast. Someone that once she makes her decision on something is not wishy-washy in the least. It makes her a cool character to read.
