The director of the youth idol drama asked the hero and heroine to ride "dead cars" through the streets, parks and other scenes in South Korea. However, due to the difficulty in operation, the prop designer combined the color of the dead car, the speed of the road car and the mobility of the mountain bike, and invented the "cool car".

After the Korean drama was broadcast in China, this cool flying car was deeply loved by young people in China. However, in the market of China, there appeared a kind of "fake flying car" with poor performance and low price. This kind of "fake flying car" is prone to problems such as broken frame and excessive heavy metals in human contact parts during riding, which is harmful to consumers' health.

Emma's cool flying car was introduced to China for the first time after Emma improved its appearance, speed, safety and handling. The popularity of the Korean drama "You from the Stars" has made Emma cool car popular among young people who are pursuing fashion trends in China and accepted by their parents in China. Now it has become popular among middle school students, college students and young white-collar workers in China.
