Sports Chosun had written a report claiming that the two have been dating for four years. The article reads, "Yoo Yun Suk and Kim Ji Won enjoyed a date in the vicinity of Gangnam on March 29. Yoo Yun Suk and Kim Ji Won were not aware of the attention and comfortably met up. Sharing their food with each other was a given, and they didn't even hesitate from affectionate skin ship."
The report claimed that the two first started having feelings for each other while filming movie 'Horror Stories' back in 2012 and evolved into a couple of four years.
Regarding this, both actors' sides stated on April 4, "The two of them are not a couple. We have no idea why a report like this came out."
