After their second semester final exams end, there are plans for a sleepover at Kaguya's house. But Shirogane and the others are unable to come, leaving Fujiwara as the only one who can join. While barley glancing at an upset Kaguya, Fujiwara gets excited about the totally hot butler Mr. Herthaka without realizing it's Hayasaka dressed as a man. That night as the girl talk unfolds at the pajama party, a sleep-deprived Kaguya takes on a strange mood before anyone can notice. With that energy, she calls Shirogane and ends up asking outrageous questions.

si è imbattuta in un uomo che fa sul serio...
Ecco il background del personaggio.
