 Nosaka argued that while Seita is "when it comes to reality" not a romanticist for he also becomes hungry, "objectively speaking" Setsuko, at age four, is at the period when "a girl looks the cutest" and Seita is just becoming aware of his masculinity in his adolescent period.Nosaka said that the two have an "obvious consanguineous relationship" and that Setsuko is the only person Seita can confide in.Nosaka added that "while there's a strong blood tie, he's shut out from being able to love her as a girl" and that his tension increases to high levels and therefore sublimation takes place.
