Super Junior's leader Leeteuk broke into tears as he talked about the difficult year he had on MBC Music's 'Wonderful Day'.

After going paragliding in Switzerland with fellow members Eunhyuk and Donghae, Leeteuk shared during a one-on-one interview with the producers, "There were also a lot of things I wanted to say right before jumping off. I was about to say things that I couldn't say before, but I didn't say any of it because I was scatterbrained [at the time]."

The mention of his family was what brought him to tears as he shared, "2014 is like a year that I want to erase from my memory... As I went up the high mountain, I thought a lot about how I'm a little closer to my father, grandmother, and grandfather who are up in the sky."

'Super Junior's Wonderful Day' will air its 4-episode marathon starting on December 31 at noon KST!
