According to Sports Seoul, industry insiders told them that “Seo In Guk and Sunny are currently seeing each other with ‘good feelings’ toward each other.” Reportedly, Sunny got to know Seo In Guk through his connection with Yuri, another member of Girls’ Generation who starred in the movie “No Breathing” (2013) with Seo In Guk. After completing filming for the movie, Seo In Guk naturally got to meet Sunny with Yuri and their relationship developed into romance from there.
There were also testimonies of people who reportedly saw Sunny taking care of Seo In Guk when he was hospitalized in a Seoul general hospital last month due to a health issue. Patients at this hospital stated that they saw Sunny take care of Seo In Guk overnight while he was hospitalized in the ear-nose-and-throat department. One patient said that although Sunny looked like she was trying to cover herself to hide her identity, people could immediately tell it was her. She nursed Seo In Guk for a long time and left.
Rumors of Seo In Guk and Sunny dating have also floating around the tabloid circuits for a while.
However, both sides’ agencies have denied that the two are dating, saying they are just friends.
