With a carefree outlook on life, Hiroto knows better than anyone that slowing down is sometimes the best way to move forward.

At 29 years old, carefree Hiroto Ikuta doesn’t have a girlfriend, a full-time job, or a plan for the future—and he couldn’t be happier. Hiroto’s breezy attitude isn’t easy for everyone to understand, though. In a world filled with anxiety, confusion, and grief, Hiroto and the people who surround him are all just doing their best to figure out this thing called life.

The summer weather isn’t the only thing heating up around Hiroto’s little family home. Hiroto’s best friend, Hideki, becomes increasingly worried about becoming a father; Yomogi, Hiroto’s new friend, starts feeling the stress of her busy real estate job; and Natsumi’s friend Akari struggles with her self confidence. With everyone under so much pressure, Hiroto’s chill attitude is downright frustrating. But with things about to reach their boiling point at the Asagaya Tanabata Festival, Hiroto’s positive outlook might be just the thing they need to relieve the tension.
