Keita falls ill just before his exams and Ako and Riko get out of school to nurse him back to health. However, his recovery is hampered by the twins fighting to earn his affections. Both of them end up licking the sweat off his body, which passes the cold to them while Keita makes a full recovery. Yūzuki, who proctors the exam, is surprised to find Keita present. While Keita takes his exams, Ako and Riko remember how Keita supported them when they were taking their exams. After returning from his exams, Keita gives his thanks to the "sleeping" Ako and Riko.
