On this day, he was asked, "Which of the female actresses with whom you worked do you find the prettiest?"

So far, in relation to dramas, Seo In Guk worked with Eunji ('Reply 1997'), Yoon Sae In ('Rascal Sons'), and Kim Yuri ('The Sun of the Master').  

Without hesitation, Seo In Guk responded, "Yoon Sae In . . . She is tall and both cute and sexy.  She is really charming . . . We had a kiss scene and afterwards, when it was time for me to get up, my legs were shaking so I had to use a bit of strength to stand up." He also mentioned he would like to work again with Kim Yuri.

Seo In Guk was also asked, "As an actor, wouldn't there be a time when you'd have to do a same-sex kiss scene?  If such a time did come, would you do it?"

Seo In Guk replied, "I do have the intention of doing it . . . I've thought about it . . . In the drama 'Reply 1997,' Hoya's character had a one-sided love for me, right?  After that drama, I played a role in a MV in which I had a one-sided love for Ahn Jae Hyun . . . At that time, I thought about it for a long time."
