At Last, the Real Thing! (S01E10)

With Keita under the weather just before the crucial exams, Ako and Riko take it upon themselves to care for him, hoping to nurse him back to health. However, Keita is not thrilled about his slow recovery, especially with his two stepsisters vying for his affection. In a rather unusual turn, they end up sharing a rather intimate moment by licking the sweat off him, inadvertently catching his cold in the process. When the final exams arrive, Yūzuki is taken aback to see Keita present. As he takes his tests, Ako and Riko reminisce about how Keita supported them during their own exam struggles. Afterward, Keita expresses his gratitude to a resting Ako and Riko, leaving them surprised as he quietly departs.
