Actress Oh Yeon Suh shared that the relationship rumor with actor Lee Jang Woo this spring, although it was hard for her, was an opportunity for her to look back on herself and mature. Oh Yeon Suh in an interview on Monday, December 23, 2013, spoke of the relationship rumor with actor Lee Jang Woo that hit the news in January of 2013. Oh Yeon Suh said in the interview, "Because there has been a long time since the rumor came out, I do not think it is polite for the other actor to mention the person again. I feel cautious to speak about this again."

Previously Oh Yeon Suh was rumored to be dating actor Lee Jang Woo, whom Oh Yeon Suh had filmed the MBC everyday drama "Oh Ja Ryong Is Coming." Oh Yeon Suh at first said through her agency that she is going out with Lee Jang Woo, then repeated her response saying that she and Lee Jang Woo are only good friends, making the audiences confused.

Oh Yeon Suh was filming MBC entertainment program "We Got Married Season 4" at the time with Lee Joon of the male idol group MBLAQ, and the relationship rumor with Lee Jang Woo led her to resign from the program, because the audiences questioned the sincerity of Oh Yeon Suh and Lee Joon's marriage.
