My dear, I have been waiting for you all my life, and now, I can finally say to you in person, "I love you, and I have no regrets in accompanying you throughout your life, and... I miss you very much."
This is a love between a man and a ghost. There is a person who, at the end of his life, sees the person he loves getting married. He is old and has waited for too long. Fortunately, he did not miss it and said I love you to him in person... This is enough.
