Song admitted at one point during the interview session that she felt "extremely sorry" towards female lead Han Hyo Joo. She said, "I don't think it'd be right to pass any kind of judgement toward Han Hyo Joo. I just feel extremely sorry towards her. There were so many scenes of her running crazily all over the place, sobbing, and just using up all her emotional energy. I felt sorry towards her until the drama's conclusion. I really wanted to show lots of happy scenes but as I was following my story, there were probably many difficult scenes [for Han Hyo Joo]. It's very unfortunate. I also wanted to see the two leads be all lovey dovey and go on dates with a peace of mind."
Song also thanked Lee Jong Suk, saying, "Thank you. In the beginning, I sent [Lee Jong Suk] a lot of text messages telling him that I was really blessed [to work with him]. What would I have done had Lee Jong Suk not looked like his webtoon character? Honestly, it was really important to find a person who looked like he stepped out of the pages of a webtoon, and Lee Jong Suk really brought that aspect to life [on screen]. I'm thankful he was able to do that."
