South Koran artists Lee Sung Kyung and Nam Joo Hyuk admitted their relationship in April, but they have broken up, according to  YG Entertainment. Some industry representatives revealed they are too busy to maintain the relationship. 

YG Entertainment has released an official statement: “We checked with Nam Joo Hyuk and Lee Sung Kyung, and it is true that the two recently broke up,”  but the statement didn't reveal the exact reason for their breaking up. 

Some industry representatives revealed that they naturally grew apart due to busy schedules and have decided to keep a supportive senior-junior relationship.

The two model-turned-actors had fallen in love with each other during the cooperation of the Korean drama “Weightlifting Fairy Kim Bok Joo”.
