Spring break. Futaro is trying to keep a distance from the sisters, but he runs into them during a family vacation at a hot spring hotel.
I'm going to figure you out myself, 
even if I get no one else.
Je dois trouver par moi-même
qui tu es.
Quero, pelo menos, conseguir
saber sozinho quem é você.
Я различу вас сам, без чужой помощи.
