Looking forward

Recently, I watched a drama. The story is about a man attended a wedding of the girl he loved, but unfortunately he was not the bridegroom. He felt so regret about the thing that he haven’t done before. So, he was given chances to go back to the past. After few times trying to change the future, he failed. He realized that something was destined to happen, no matter how hard you try, the ending is still the same. So finally, he decided to accept the truth with an open heart.
As a conclusion, the pass thing can never be correct so we must learn through mistake and looking forward so that we will never repeat the same things again.
