Summer is clearly You's favorite season above all the others. Fun games with friends, beach outings, no school, and most importantly, her father's return. Every second day of summer, You Watanabe waits eagerly on the Uchiura harbors for her father to return home. Those summers were often filled with brilliant memories of the two of them. You loves those memories too much, so much that she's willing to wait three seasons and one day for him. One day, he doesn't show up.
