When Su Wantang woke up, he was imprisoned in the basement of a cliff manor.
The woman who imprisoned her is Shen Manyun - once a close friend, now a nightmare. She doesn't kill her, she just enjoys her pain day after day.
"You had everything before, but now you only have me."
But Su Wantang never accepted his fate. She began to make plans - to seduce Shen Manyun's husband and get close to the taciturn housekeeper Ji Linyuan. She uses psychology to gain insight into everyone's weaknesses and weave a web of escape.
Until that night, the bottomless swimming pool of the manor swallowed up all sounds.
Until Ji Linyuan walked into the interrogation room and said calmly: "I killed the person."
He exchanged the freedom of the rest of his life for her freedom.
The abyss is never at the bottom of the pool. The abyss was in her heart.
Intention: The abyss is never at the bottom of the pool, but in the human heart.
