The summer weather isn't the only thing heating up around Hiroto's little family home. Hiroto's best friend, Hideki, starts growing increasingly worried about becoming a father; Yomogi, Hiroto's new friend, begins to crack under the stress of her busy real estate job; and Natsumi's friend Akari struggles with her self-confidence. For people under so much pressure, Hiroto's laid-back demeanor can be downright frustrating. But with things reaching their boiling point at the Asagaya Tanabata Festival, Hiroto's positive outlook might be exactly what everyone needs to relieve the tension.
