I like a city probably because I like a person. Because of you, I choose to stay in Q City. The air here seems to be filled with your breath. I want to watch the rising sun dye the city with you, and I want to watch the sunset dye the city with you. This is a story about forgetting and remembering, past events that are difficult to explain, and scenes of sadness condensed into soft thorns of love. Everyone who has no courage to love has an impossible person living in his heart. Every impossible person is the soft thorn in our hearts that we least want to touch. It's not that feelings can't withstand time, it's that time can't withstand fickle changes. The time of reincarnation is condensed into the afterglow of love, and this book is dedicated to those lovers who are out of reach.
