Is there someone in this world who knows your ups and downs, your sorrows and joys? An Yi (played by Zhou Yiran), an assistant architect in Beijing, and Gao Ang (played by Shi Boyu), a tuner in Germany, were connected by brain waves due to an accident. From then on, they shared hearing, taste, and touch magically. The days of "forced binding" made them confused and full of jokes, but they also became the people who understood each other the most because of their constant companionship... But a misunderstanding caused a gap between the two. Faced with the long distance and the unknown future, will they firmly go to each other's world? Thank you to those who see through us but always stay with us.
