Two souls, Li and Si, live in the same body. They dislike each other and always want to drive each other out. However, they have no choice but to borrow each other's strength at certain times, and eventually become friends who share the same hardships, life and death.
Li: world-weary, pessimistic, indifferent, unfeeling, and will be punished by "hypocrites"
4: Positive and optimistic, irritable and punching whenever he disagrees with you, "true temperament"
PS: Anyway, neither of you are good people, just writing this for fun~
Intention: A real experience, but A Si is my imagination from beginning to end
