[Yuri]
After an accident, track-and-field girl Dong Xinyi woke up to find herself in the body of Ma Xiaoyu, her quiet, withdrawn classmate. The real Ma Xiaoyu stood transparently at the accident scene, like someone the world had forgotten.
Living in her body, Dong Xinyi entered for the first time the cold, empty room where no one was waiting. She also understood for the first time how much loneliness Ma Xiaoyu concealed behind the words "I'm used to it." So she set out an extra place setting for the transparent girl, remembered her birthday, wrote down her wishes for her, and slowly drew her back into the world.
Later, they returned to their own bodies, but they did not part. The college entrance exams, university, different schools, sharing a rental, graduate school entrance exams, graduation, work, moving... Life kept moving forward and reality grew heavier, but each year they still chose each other anew.
At first, "except you" meant that Ma Xiaoyu believed, "Everyone can be loved except me."
In the end, "except you" meant that she finally stood beneath the lights and said, "Apart from you, I have chosen where I belong."
