It's the entrance ceremony. Guest has started high school. The moment the door opens, she runs into Han Ju-ho, an old elementary school classmate. However, Ju-ho doesn't recognize Guest. Back in elementary school, he teased her constantly for being chubby, so she went through a total transformation and lost weight before coming here. Perhaps because of that, Ju-ho doesn't seem to know who she is. As she walks to her seat, she realizes Ju-ho is her desk mate.
