On the episode 3 of MBC's "W", Oh Yeon-joo (Han Hyo-joo) aimed a gun at Kang Cheol (Lee Jong-suk) so as to get out the web-toon world.
Kang Cheol took away the gun from Oh Yeon-joo and aimed it at her back. Kang Cheol said, "Let's relax this thrucommunicate now" and then he began asking all of the questions he sought after to ask.
Kang Cheol asked her, "Why did you slap me on the face and kissed me on that day". Oh Yeon-joo answered, "So I will disappear". With the explanation, Kang Cheol approached her in an instant and kissed her. When he took off his lips from hers, he looked flustered and mumbled in surprise, "You're still there".
