With Keita ill before the big exams Ako and Riko step up to the mark by getting out of school and making Keita feel better by nursing him back to health, but a slow recovery is the last thing Keita wants as his two stepsisters fight for the place closest to his heart. Both of them end up licking the sweat off his body, which passes the cold over to them whilst Keita makes a full recovery. The final exams are overseen by Yūzuki, who is surprised to find Keita there. Whilst Keita takes his exams, Ako and Riko remember how Keita was there for them when they were taking their exams. After returning from his exams, Keita gives his thanks to a sleeping Ako and Riko, who are surprised about it once he leaves.
Keita se enferma justo antes de sus exámenes y Ako y Riko salen de la escuela a cuidarle de nuevo a salud. Sin embargo, su recuperación se ve obstaculizada por los gemelos que luchan para ganar su afecto. Ambos de ellos terminan lamiendo el sudor de su cuerpo, la cual pasa el frío a ellos mientras Keita hace una recuperación completa.
