As far as I know, bipolar disorder is not something that gets cured, it's something people learn to manage and live with it. It is also a serious condition and I feel that if author wishes to use this illness in the novel, there should be extensive research involved... again, I'm no expert, but there's the Internet for more info ;) :D
The Author is Saying something to us. It's about her so-called dreams, y r they showing up? maybe my theory is right, maybe be I am rightâ right about she come back to her 1st lifetime, the modern world where she read the so-called novel is her 2nd lifetime, in 1st lifetime (so-called novel) she said in her next life she'd rather not know nor Understand Love and Affection and, thus let us remember the our FL she isn't loved by her family and, she didn't understand love and affection before transmigration. Let Us Piece Everything (so-called clue).
