Two people who loved each other were separated by their families. They each got married and had children in the past ten years. Through the "only you can see" goodbyes again and again, they finally learned to leave each other in the past.
It's not "how painful it is to miss", but "how to leave the loved one with dignity".
A girl in a wedding dress is saying goodbye, and a man about to get married is saying goodbye. Both of them completed their last confession in the most honorable way.
This story is like a cup of cold tea - it tastes sweet in the mouth, but tastes astringent after swallowing. The most touching part of it is actually not the "missing", but that both people have grown into better people through the missing. Ouyang did not become a resentful ex, and Qingtian did not become an abandoned victim. This restraint is more powerful than any heart-rending plot.
The idea: not "how painful it is to miss", but "how to leave the loved one with dignity"
