Life is full of twists and turns, but we still meet each other. In a world without light, she is cold and aloof, and he is calm and gentle. What sparks will be created in the rest of my life? In the love in this world, because I met you, the rest of my life will be full of joy. If - how can I not regret it without you for the rest of my life? Please give me your advice for the rest of my life. One day, I can live up to my trust and make your remaining years into a bowl of soup with mine, sharing the joys and sorrows. I hope that for the rest of your life, I will be a returnee, not a passerby. I only lend you one ride in your life, and this ride is for the rest of your life.
Concept: The whole story is sweet, a little heart-breaking, and has a happy ending.
