Cheng Ziyan was not without anger when he saw An Ran.
Lu Chenchen asked him: "Isn't she coming back for revenge?"
How did he answer: "I'm just afraid that she won't retaliate."
I'm just afraid she won't retaliate. She is afraid that everything she did four years ago will be sunk to the bottom of the sea and she will never miss it. I'm afraid she'll just leave again. I'm just afraid that she no longer has him in her heart.
