After one year, I finally returned to school. I thought my first day back would be full of fun, but somehow I ended up in the same class as my younger sibling! And to make matters worse, I showed something super embarrassing right in front of some random guy…! But why did it have to be Seo Jinyoung of all people?! We didn’t even talk once during the entire year we were in the same grade, so why are we suddenly getting tangled up like this now? Da-jeong’s chaotic school life begins… Please, just let me graduate safely!
