I thought it would be a vigorous love when we met in the beautiful flower season, but I didn't expect that the journey of pursuing love was out of reach. In ten years, the city has changed anew, but today's world of bustling traffic and feasting still cannot fill Shu Xiaochu's inner loneliness and desire. After waiting for ten years, everyone around him has left. After driving back, she still couldn't wait for the person in her heart. She had never been in contact, and she didn't know if his life would allow her to exist. For ten years, he knew nothing about her life, but she would always remember the person named Ji Junmo. Her computer web search engine always had only one name. After ten years of waiting, just when Shu Xiaochu couldn't bear it anymore, he appeared. Her world suddenly collapsed and everything was chaotic and different. And how many people were suffering on that Christmas Eve ten years ago? Whose eyes did Shu Xiaochu's heartbreak fall into? We haven't seen each other for ten years, and we don't even have time to say "Long time no see". We haven't seen each other for ten years, but we still remember ten years ago. Is it really heartless, or is there another secret? Shu Xiaochu, Ji Junmo, Shi Lei, Ding Ding, and the quiet girl standing behind him on Christmas Eve, who is right and wrong? When the relationship was no longer so pure, it ushered in ten years of emotional entanglement. The hurtful drama, the heart-wrenching waiting, and the appearance of being impatient to return to China always come by mistake. Whether to leave or stay, it no longer seems important. What matters is who is in whose heart for ten years.
