The Boy Next Door

Someone from the next door who I almost spent the night with while drunk turned out to be Woo-gyeom Jung, the little kid who lived in the neighborhood 12 years ago. But Woo-gyeom, who I met again after 9 years, is a bit strange. He asked me to pretend to be his girlfriend and then kissed me right away. Now he says he wants to be my real boyfriend. How can I date you when you're 6 years younger than me? How can Jin-eun avoid dating Woo-gyeom, who is like a bulldozer?
