However, Wataru is approaching adolescence and is beginning to feel annoyed by Miya's affection... One day, when Miya shows off her stupidity in front of her friend, Wataru reveals her accumulated dissatisfaction with her mother. The two then fight, but under the same roof...lol lives without conversation are so suffocating...
