Mei and Yuzu study together at their house so Yuzu can place in the top 100 on their exams and keep their grandfather happy. However, after their kiss of mutual yearning, Yuzu can't concentrate at all.  Steeling her resolve she asks Mei what that kiss meant only to get coldly brushed off. Feeling depressed, Yuzu heads to an arcade with Harumi, but her mind's distracted. There, she reunites with her childhood friend, the second year middle schooler, Mizusawa Matsuri.
My beloved little sister 
is as cold as ever today.
Meine geliebte kleine Schwester

Mi querida hermana
vuelve a ser tan fría como siempre.
Mi querida hermana

Моя любимая сестрёнка
и сегодня холодна как холодильник.
