Seven survivors, a cruise ship that never docks, and five doors to the past.
Some people owe an apology, and some people owe a rescue.
Shen Qinan didn't know how the system would repay the "I'm sorry" he owed his sister bit by bit.
Five Doors - the obsession waiting for the plum blossoms to bloom in an abandoned mental hospital, the black swan that cannot come to an end in the school ballet, the male actor with a beauty as a shell and an assassin as a heart on a stage in troubled times, a mother crushed by rumors in a quiet village, and the truth about the amusement park accident five years ago -
Every door asks the same question:
If going home was just an illusion, would you still choose to wake up?
Concept: Death does not mean the end of life, it may also be a new life.
