The KJ and TY's heartwrenching breakup scene in episode 18
KJ: Make a wish.
TY: You carry coins with you now?
KJ: Don't you know? Ever since we bought the red piggy bank, I've been carrying coins with me. I'll bring them to you next time. Now, make a wish.
Why? Touched? Make a wish.
TY: "Please let him believe my words, so that he won't get hurt."
KJ: What did you make?
TY: I wished for a rich guy
KJ: What? I'm not enough for you?
TY: Yeah, kind of.. I got bored, and I'm greedy
KJ: Not only are you greedy, you are also getting bold
TY: Let's take a photo with this greedy and bold woman
KJ: No, I won't. I said no, I'm getting mad
TY: Just one will do, come. After me, "Hawaii.."
TY: Hawaii, Waikiki, husky
KJ: waikiki, husky
TY: I want to eat ice cream, can you get me?
KJ: Where do I get it?
KJ: What flavour?
TY: "Lost me, haven't you? You can't find me anywhere. You're a lost child now, because I've abandoned you. Let's break off the engagement. I'm tired, your father, sister, and Yun-ah have made me too tired, and we've hurt Su-hyuk deeply. For the sake of my own happiness, I've hurt many people. Come to think of it, I've been too silly. I thought love can feed me, shelter me, and always bless me with happiness. But I was wrong, there are still problems love can't overcome. I'm tired. I chose to leave to let my conscience feel better, will you forgive me? You, too, will be alright soon."
