We open with Jieun feeling a bit glum that she can only reach Hyunwoo if he’s within a 2.5km radius. She thinks to herself that their relationship is similar to the walkie-talkies; it only exists when they are right next to each other.
As she’s leaving the restaurant, she meets Sangyeob, who immediately ascertains that she’s feeling under the weather and offers to drive her home or take her someplace to cheer her up. Jieun thinks back to all the times that Sangyeob has acted strangely and realizes that he was trying to prevent her from seeing Hyunwoo with his ex-girlfriend. She refuses his invitation, but says with a smile, “I really have a good friend in you.”
