- So, the first time I saw Yoon Yoonjo wasn't in the classroom. 20-year-old rich returnee Yoo Surin and 19-year-old poor model student Yoon Yoonjo keep catching my attention. If it weren't for my mom's independence proposal, which was conditional on graduating safely, we wouldn't have had any connection at all. The daughter of the building owner and the part-time convenience store worker in that building, a delinquent and a model student, twenty and nineteen, Being opposites made me think that if I just took one step closer, I could have something. So I said it, then I regretted it, and then I liked it. - Hey, let's hang out until you graduate. The only person who rolls their eyes and says no to Yoo Surin's words is Yoon Yoonjo, which makes it even better. Yoo Surin, who believes she must have what she likes, decides to go straight for Yoon Yoonjo. On the other hand, Yoon Yoonjo, who has nothing and can only study, His only goal is to leave the city where he is living by studying hard and live a normal life. In that life, Yoo Surin, who knows nothing but herself and doesn't care about others' opinions, keeps saying with her whole body that she wants to take up a spot. I didn't want to get involved, but it started as a light relationship that was annoying, and as time goes on, the size that Yoo Surin occupies keeps growing. Can the two of them, standing at their respective ends, truly fall in love in the end?
