Ko Ah Ra and Jung Woo couple, who shocked the audience with the reverse storyline of how they were not real blood-related siblings, foreshadowed the first love.

On the third episode of tvN's "Reply 1994," aired on October 25, 2013, Na Jung (Ko Ah Ra), who didn't know any man except for the basketball player Sang Min, realizes her feelings of first love for Sseureki (Jung Woo).

When Na Jung goes into Sseureki to wake him up, the atmosphere between the two was quite different from when they were siblings, picking on each other all the time. Na Jung, who started to feel something for Jung Woo, goes into his room to wake him up. But Sseureki, who didn't want to wake up, hugs Na Jung and snuggles her. While the two shows a romantic scene for a little bit, the two start to play with each other again, biting on each other's arms.

The audiences are looking forward to how Na Jung and Sseureki would weave out their first love story.

tvN's "Reply 1994" airs every Friday and Saturday night.
