Jang Bo Ri/Lee Jae Hwa couple from Come! Jang Bo Ri. Episode 21.

 

The first scene of this episode happens after Jae Hwa finds out Bo Ri isn't married. He is so happy that he goes to help her when she leaves to go shopping.
Bo Ri takes advantage of his help and makes him carry several items. She even has him carry a big heavy watermelon. Jae Hwa becomes dehydrated and asks for water but Bo Ri, not realizing he is serious, continues to walk ahead. Jae Hwa then faints and Bo Ri goes to help him. Not having any water around, she breaks the watermelon and has him eat it. As he starts to get his senses back, he realizes Bo Ri was worried about him. While she stares at the watermelon seed stuck on his face, she imagines it being stuck in a funnier place. As she thinks about it being stuck on his tooth, he thinks she wants to kiss him.

Bo Ri: Do it.
Jae Hwa: Do it? Do what? Here? How daring. Then...should we do it lightly?
Bo Ri: You need to open your mouth.
Jae Hwa: What? No, I can't do that.
Bo Ri: It's fine. Just open it a little and I'll do it.
Jae Hwa: You will?
Bo Ri: (nods head)
Jae Hwa: I've never had this experience before.
 

Bo Ri takes the seed and puts it on his front tooth. She laughs as he realizes what she was up to. He gets another seed and puts it on her face. They continue to play around and make fun of each other. He tells her to wait because just like before, he will kiss her on a beautiful day.
