From an artist's point of view, Daisuke thinks, Riku Harada is not beautiful. In the rain, crying, her hair does not cling to her face, strands sticking to her cheeks and partially covering her eyes. You cannot see the distinct spot where heated tears flow faster than rain ever could, and her clothes do not tighten just-so.
No, that beautiful scene could only be portrayed by Risa. Her hair is long, and seeing usual-curls straight would be something amazing. Her eyelashes are thick, and he's sure she cries prettily. Always-fashionable clothes probably would cling to her just-so, because it's Risa, and can be no other way.
But he doesn't love Riku. And he doesn't love Risa.
And the one he finds by the fountain, wiping his eyes despite the rain, white shirt transparent and clinging, is Satoshi. And Satoshi is blue, and even if the Harada twin's are brown, mahogony, and match his own red, blue is contrast. And blue is the best color for rain.
