Ten years ago, Duan Yijun said: "Su Yi, how many people in our circle are wholehearted? When you are young, you can just have fun. When you get older, you still have to marry a woman. Su Yi, don't be stupid, it will be bad if you are too serious."
Ten years later, Su Yi said: "Yi Jun, I don't hate you, but I don't love you anymore. So let's just do it. It feels good to be friends with you."
But will love really be what they say, and can they really control their feelings?
When there is a ten-year gap between the two, will the two reunited find their love? Everything is still unknown...
