In a seemingly ordinary small town, Kim Bong-seok is a boy who is born with the ability to fly.However, this extraordinary secret has become a heavy burden on his mother Li Meixian's heart.She knows very well that once Feng Xi's ability is exposed, it will not only attract countless eyes, but may also bring endless trouble and danger.In order to protect his son's safety, Li Meixian took various measures in an effort to bury this secret deeply.
As a result, Bong-seok's daily life has become cautious. He must always control his impulses to avoid inadvertently revealing his flying ability.However, in a chance encounter on the bus, he met Zhang Xixiu, a lively and cheerful girl.The two people's eyes met, and Feng Xi felt an inexplicable feeling in his heart.At this moment, he almost floated due to his heartbeat. Fortunately, he controlled himself in time.
At Kyungwon High School, Bong-seok's teacher seems to be carrying some kind of secret mission, and the head teacher's advice to Hee-soo confuses him even more.He suggested that Hee-soo enroll in a sports university, which seemed to have some unknown connection with Bong-seok's superpowers.After school, in order to avoid exposing himself in front of Xixiu, Bongxi took the initiative to help her pick up her schoolbag, and the relationship between the two inadvertently became closer.
Xixiu decided to take the physical examination, partly to pursue her dream, and partly to reduce the burden on her father.She didn't know that this decision would connect her and Kim Bong-seok's fate more closely.
At the same time, Frank, an American CIA agent, came to South Korea to carry out a mission to assassinate a person with super powers.His first target is Zhenchuan, a young man who also has super powers.Although Zhenchuan showed great ability, he was still defeated by the experienced Frank.This incident aroused Li Meixian's alert. She realized that someone was starting to eliminate superpowers. In order to protect her son, she must start making preparations.
