Lin Jingchan always knew what she wanted.
She was never indecisive, but once, she wanted to keep something with a lie that was childish enough to be easily exposed, maybe a promise about "the future".
Zhou Xiasheng has always known what kind of person Lin Jingchan is.
She was decisive, brave, and the toughest life he had ever seen. So when she chose to leave, he didn't hold her back. He knew that she should run for her own life, and that she should be like when they first met, with her long hair ruffled by the wind, smiling at him in the sun, forever free.
Philosophy: Love is freedom, and lies that can be disguised as promises tend to last longer.
