What is deep affection, what is sincerity, what is love? Love, this word, seems simple but full of weight. I'm afraid no one can explain clearly what love is. Love is all-encompassing, and no one can capture its shape or perception, but it contains all the flavors of life. Sun Muyan, a modern woman living in the 21st century, was the only child in her family. Until one day... It was still her home, but where should she exist? She saw all the things there, as if she was walking there too. In that year, she met him, Han Tianyu, and the two met and fell in love... Suddenly she woke up from the dream, leaving only the shining light in her moist eyes, and the cold touch in her hands brought a tingling pain... That dream was so real, so beautiful, she knew it had indeed existed. She thought of 1998, that day, those words, those memories that had long been forgotten by her, and it turned out that that person was already waiting there. Finally, she was relieved and no longer obsessed with searching. She understood that the sincere love would remain in her heart forever. She smiled, like a flower still standing proudly in the cold wind. What disappeared with the wind was not the fallen leaves and petals but her immature past. What remained was not the upright figure but the unforgettable love... Look, that person, I am waiting for you to come back!
