Zhou Quan and Li Mingxi, Qin Ran and Wu An, two pairs of lovers with different starting points in life. When they meet each other and fall in love with each other, how should they make a living together? There is hurt, there is warmth, there is betrayal, there is loyalty, there is separation, there is reunion. We met at the best time and grew up at the most beautiful age. There are two things in the world that cannot be looked at directly, one is the sun, and the other is the human heart. ——Kuigo Higashino
