Yeongseon visits Youngkyu to learn English. While Young-gyu explains hard, Young-sun has another problem, such as applying nail polish to his nails. Yeongseon goes to the toilet and comes out to see the quintessence at first sight. Younggyu struggles to come up with a way to make him study properly. The next day, Young-gyu beats his calf in front of Young-sun and says with all the misery that everything is his fault. Young-kyu becomes crying when Young-sun doesn't keep up and just watchs him. Meanwhile, Young-sun visits So-yeon and compels him to break up with Oh-jung and asks him to marry him. Oh Jung puts a condition to study hard and meet him when he enters college. (Source: SBS)
