Rachnea rapidly integrates into the Kurusu household, prompting Miia to feel jealous of her overly friendly behavior. Despite this, Miia cannot compete with Rachnea's mature composure. Centorea initially states she has no objection to cohabitation. However, her emotional control fails when Rachnea engages in relentless sexual harassment of Kimihito around the clock. This continuous tormenting prevents Centorea from maintaining her composure, leading to a breakdown of her initial acceptance of the living arrangement. The situation highlights the strain on the household dynamics as new members interact with Kimihito in ways that disrupt the existing balance.
