On the October 26, 2013, episode of tvN's "Reply 1994," Sung Na Jung (Ko Ah Ra) confessed her love for Sseureki (Jung Woo) to him on April Fool's day.

On this day's episode, Sung Na Jung, coming home from school, finds a stuffed seal doll that Sseureki had gotten for her to cheer her up from her brother's death, which happened a year ago from the day.

Sung Na Jung goes into Sseureki's room and asks him, "Did you buy that stuffed seal doll for me?" She then added, "I have something to tell you. I like you, and I love you." Sseureki, who just heard an abrupt love confession, pinches Na Jung's cheek, saying, "Do you want to die? Did you think I wouldn't know today's April Fool's day?"

Near the end of this day's episode, in the present time of 2013, Na Jung's husband's name, Kim Jae Joon, was revealed in a meeting of Na Jung and the five men, arousing curiosity of many audiences.
