Fang Hui is an interior designer. At the age of 26, she met Cheng Junfan, 38, and a love affair between the slow-hearted woman and the slow-warming man began.

When the wind of extramarital affairs blows across the lake of marriage, everyone is different again. But when the wind blows, I realize: what is lost is precious.
