Wenseul: High School dorks

Wendy and Seulgi are in high school. Wendy is extremely popular throughout all grades and is in every sport. Seulgi however, is the school nerd, and gets all A's. Since Wendy puts all of her time and effort into sports, her grades are terrible. Since Seulgi gets all A's, the principal chose her to tutor Wendy and help her bring her grades up.
