In the early stage, work as an undertaker safely without being disturbed by anyone. Escape from the past and maintain the illusion of "having nothing to do with the world."
Mid-term: Find out the truth about the serial abnormal death case, confirm the cause of death of your mother, find out the source of your own abilities, and find "the reason to live instead of just "the excuse not to die"
In the later period, there is a head-on confrontation with the Yan family/the mastermind behind the scenes. Accept all of yourself (abilities, past, emotions) | Become a person who "chooses to live among the crowd", rather than someone who is forced to be alone.
