Even if the finale is happy, we will never be the same again... Everything has changed. The final HE is just the last comfort for the parties involved and us...
If life is my novel, I will definitely start over. It will be the same encounter, the same life, and I will choose you again, but this time I will definitely give you a different ending, because I believe that even if only one party changes direction, the ending will be a happy ending. I have the confidence to change it.
But life is not a novel, and we can't go back, so we can't make up for the regrets. Even the initial hatred will disappear after so many years. Hatred will not disappear, but will form regrets, so he can't wait for the ending, and there is no HE in the ending...
Intention: Things are the same and people are not the same.
