In a world where the rain turns everything to black and white, only those to whom we are connected radiate with colour amidst the rainfall. Dol, who doesn't believe in the rain colour-verse, therefore has to stay covered up during the rainy season so as to avoid happening upon his soulmate, Sun. Sun is a rider, bright as the sun, shedding his warmth on all that surrounds him. Sun's cuteness will gradually change Dol's world. In the end, it will be a warm and more pleasant world.
