what if it turns out that now is MC's third life?
first life when she was a college student, second life when she entered the novel, but because she was brainwashed so she forgot everything or in the second life she didn't remember her first life. Then she died, so she went back to the past aka the third life now.
I speculate like this because seeing the tower master's words are really suspicious, and it's just my opinion tho ╮( ̄▽ ̄)╭
