Dear Mother

Summer vacation is over, and the new school term begins. But Miya is absent, sick with a fever. Riru and Koyuki, along with Arisa and Marika, worry about her. As Arisa remembers the day Miya first came to the Kounokura household, Teru and the others care for Miya at home. Feverish and barely conscious, Miya hears a familiar voice calling her name... Her mother's.
