Soubu High's queen bee, Yumiko, has come to the Service Club with a forlorn expression and a request: Find out Hayama's plans for his educational track. Now it's up to Hachiman to deduce the truth, and he's well aware that cracking the flawless facade of the most popular guy in school is no small feat. But the attempt may just lead to some revelations -- about Hayama, himself, and the weight of expectations.
