On this day's episode, Joo Wan carried drunk Shin Joo Yeon home. After putting her down in bed, he said, "Why are you clenching your fist when you sleep?" and touched her hands. Joo Wan then took out her pajamas in the closet. Joo Wan then said to sleeping Joo Yeon, "I do mean well. I just want you to be comfortable when you sleep," and started unbuttoning Shin Joo Yeon's dress shirt. But then Joo Wan stopped unbuttoning her dress shirt saying, "I cant. My heart is beating too fast," and left Shin Joo Yeon's room.
