Excited! First Visit Day Today is class observation day at Paradise Academy. Himari's family, including her father, mother, and younger sister Hiiro, all decide to come. The Himari family was in full spirits and came early in the morning to tour the school. Then, Hiiro bumps into Yuuma, a boy from the elementary school who is about to be late. At that moment, Hiiro didn't notice that the lipstick had fallen out of his pocket. That lipstick was a secret that was important to Hiiro.
