During a break at their part-time job, the topic “Have you graduated from being a cherry boy (virgin)?!” comes up. Yamazaki holds back, knowing that his innocent junior, Higashino, doesn’t even understand what “cherry boy” means… However, the moment Higashino finds out the meaning, he becomes extremely sulky. Later, as Yamazaki tries to console him over drinks at home, the tipsy Higashino turns the question back on him: “Senpai… have you graduated?”
