Hae-yoen Gil becomes bad mother as she blocks daughter Son Ye-jin's love Kim Miyeon (Hae-yoen Gil) in the 10th episode of JTBC's gilt drama, Beautiful Sister Who Buys Bob Good (played by Kim Eun/director Ahn Pan-seok), which aired on April 28, vehemently opposed the love affair of her daughter, Yoon Jin-ah (Son Ye-jin). When Seo Jun-hee (Jeong Hae-in) and Yoon Jin-ah knelt down in turn, Kim Miyeon noticed the secret love of the two, but the reaction was unexpected. Kim Miyeon was angry at his son Yoon Seung-ho (who was a friend), saying, "Did you know that?" But then he took him into the room with anger, saying, "Why are you playing games without studying to do that?" A thorough disregard for the Seo Jun-hee. Yoon Jin-a was embarrassed and once he saw Seo Jun-hee, when Yun Jin-ah returned, Kim Miyeon hit his daughter with anger that "Jun-hee is going to be a party." Kim Miyeon was hurt by his arm and found the emergency room that night. Yoon Jin-a had taken care of Kim Miyeon, who had been treated by Seo Jun-hee, but Kim Miyeon was still cold. Kim Miyeon said her husband, Yoon Sang (Oman Seok), "What is wrong with meeting Junhee? I was the last to know, "he said, and when he responded insignificantly, he kicked him out of his room. “Yoon Sang, like Kim Miyeon, was also opposed to the relationship between Yun Jin-a and Seo Jun-hee,” he said. Kim Miyeon met Seo Jun-hee sister Seo Kyung-sun (played by Jang So-yeon) separately and laughed, "I did not win it, but I think they are doing well and doing things well. “Yes, you’re not a cloudy kid, but it’s strange,” he said. “Jun-hee still needs to be ironed out and held up. I thought you said that you would be responsible for Jun-hee's life properly. " Seo Kyung-sun, who has really regarded Kim Miyeon as a mother for a while, quietly shed tears when he heard Kim Miyeon's words quietly because there was no other refutation. While Seo Kyung-sun was tearing, Kim Miyeon was angry, saying, "Where is your mouth?" And to her daughter, Yun Jin-a, she was asked to see the confrontation on the weekend. Yoon Jin-ah did not listen to it as "horrifyingly childish."
