Ako attempts to assist Keita in studying to boost his passing chances, though both struggle to maintain focus. After Ako displays her chest to motivate him, Keita becomes distracted during class. She then tries writing notes on her body, which helps him perform better on tests despite his embarrassment at school. When Keita compares a kiss from Ako to a penalty game, she becomes angry, corners him, and tricks him into a wrong answer to enforce the penalty. Their interaction is interrupted by Riko, who offers a snack she prepared but is inedible. Ultimately, Keita’s grade improves slightly, and he credits Ako for his success while Riko watches with jealousy.
