The first time Hyung Kyu and Dokko Jin met, Hyung Kyu immediately recognizes him and Jin finds out that Hyung Kyu was the mysterious Ding Dong from the Pikachu quiz call. Ding Dong quickly observes that Jin’s mustache looks like the character 소 (so), which also means cow. Looking at his reflection and discovering that the boy is correct, Jin becomes so self-conscious that he cannot help but cover his chin. Ding Dong almost tells Ae Jung about the 소 but Jin hushes him and tell him to keep it a secret.
During a CF film shoot, President Moon and Ae Jung rush to the set where the staff is having some difficulty in getting Jin to cooperate. The director needed Jin to shave off his ‘stache but he refused to. His facial hair is his trademark. Complimenting Jin and telling him he’d look like a flower boy (aka pretty boy), the staff continued to try to encourage him shave it off. Jin looks to Ae-Jung for some reassurance but she is uncertain and keeps quiet to the dismay of the staff.
Ae Jung goes to convince Jin telling that he would handsome. Jin agrees to shave but tells Ae Jung it is only for her. She feels burdened to shoulder that responsibility but would rather have the shoot happen easily then be mobbed by the irritated staff.
Soon after, at the request of the director, Ae Jung allows the shoot to borrow her lips for the visual look of the shoot. She must leave a lipstick print on Jin’s cheek near his lips. Here Ae Jung starts to become aware of her attraction for him, which was previously blinded by his butthole attitude.
When Jin discovered the truth about the Thump-thump song (because it was played during his heart surgery) he thought that there was now no longer a reason for his heart to race for Ae Jung anymore. The spell was over and he was no longer a slave to his feelings for her anymore. Ae Jung disappointed to hear this as she recently discovered her feelings for him, tried to test his heart out by leaning on his chest. Instead, Jin says he feels nothing for her and that he felt wronged, accusing her for making him shave his 소 mustache that was his trademark. Nevertheless, he is pleased that the tables had turned and that Gu Ae Jung was now pursuing him.
A real cow makes its entrance during their second date out. Being a witness to their secret date, Jin tells the cow if the story leaks out he will sue the cow for libel. Laughing, Ae Jung tells him that the cow doesn’t understand unless he speaks to him in cow-speak. Jin moos the threat but takes a picture with the lucky beast to keep as evidence of such a great outing.
