If you are interested in swimming or possibly seeing Lee Jong Suk and Seo In Guk dive into a pool, the new teaser for the film "No Breathing" may prove to be very entertaining.
It's only natural that the teaser should feature the two stars in their swimsuits as the film, which also stars Girls Generation member Kwon Yuri, is about competitive swimmers.
"No Breathing" is a term that means the state in which a competitive swimmer stops breathing when they are swimming.
Lee Jong Suk plays Woo Sang, a national swimmer who is very competitive by nature. Seo in Guk plays Won Il, a swimming prodigy who has not always been so dedicated but decides to compete with his friend on a national scale.
