Yuu, Kouichirou, Natsume, and Shino belonged to the same class. Ever since childhood, Kouichirou had been taking good care of Yuu. However, the latter had a constant fear that Kouichirou might abandon him in case of poor academic performance. Due to this worry, Yuu worked diligently, but ultimately ended up with a fever. While being treated in the infirmary, Yuu created a ruckus, and Kouichirou planted a kiss on his lips. What could be the meaning behind that kiss? Natsume and Shino had been engaging in sexual acts for some time. Though they had mutual feelings, neither confessed to the other until Shino finally opened up. Would Natsume reciprocate?
