Two male protagonists, the story is bloody, amnesia, and there is an easter egg at the end that you need to decipher on your own.
"Jiang Jialing should have realized that Jiang Quan doesn't love him at all and has never even liked him."
Concept: The cycle and shackles of trauma
The protagonist is burdened with the huge psychological trauma of the death of his loved one. He does not choose reconciliation or legal channels, and instead uses intimate relationships to commit mental abuse. Old tragedies give birth to new tragedies. Trauma is not healed, but transformed into new injuries and passed on.
