The young man with hair the color of the sunset was like the wind when he fell into the water while photographer Suguru was taking pictures in Enoshima. Just as Suguru was worried about whether he should jump, the young man, Kengo, carelessly said "It seemed like it'd feel good" and smiled like the sun. Although they parted ways that day, they met again by chance at a shop Suguru stumbled upon. Even though Suguru had not yet found a place to stay, he received an invitation from Kengo to stay at his house.
