On this day, Lee Jong Suk revealed, "To be honest, I wanted to be Seo In Guk's character, Won-Il.  I believe he made the character as alive as the character's charms warranted."

He also said, "Through this piece of work, I worked with both Seo In Guk and Yuri, but aren't they singers?  Honestly, I had some prejudice against singers who act, but now that prejudice has completely disappeared."

Seo In Guk said, "Lee Jong Suk has more experience than I do and he is my sunbae.  I learned a lot from him.  Even while filming, I think we did well while encouraging each other.  In my personal opinion, I think our breathing was incredibly good."

'No Breathing' is a passionate movie about two competitive swimmers who want to be the country's representative and dream of setting a new record while fighting for the same girl, who will be played by Yuri.  

It will be released on October 31 so make sure to check it out!
