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

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. This year's Asagaya Tanabata Festival is right around the corner, but the upcoming festivities are the last thing on anyone's mind. While Hiroto and Hideki break into a heated argument over their new zombie film, Natsumi must deal with the fallout of a fight with Akari that may threaten their entire friendship. Will these four friends find a way to put aside their differences, or will their relationships melt away in the summer heat?
