Three weeks had passed, and both the Frenchboy and the Englishboy had begun developing...feelings for one another. As always though, they had been careful not to touch at all, for fear of being the only one to see colour, which happened sometimes. It happened to Gilbert with Eliza, who saw the colour with his friend Rodrich instead. He was heartbroken, and decided he had to keep looking, though he doubted he'd ever find anyone. "Arthur?" Francis asked one day when they were relaxing at the Frenchboy's house.
"What is it, frog?" Arthur asked, taking his chance on Rainbow Road as they were playing Mario Kart.
"Have you seen the colours before?"
"I-I...yes. But I was the only one and it was brief."
"With who??"
"...Alfred. That's why I stopped talking to him," Arthur blushed. His American friend was so attractive to him, but...when Alfred didn't see the colour, Arthur lost hope in finding someone.
"Well...I'm sorry. B-but....could we...see if we could see the colour?" Francis asked.
"I-I suppose. But you have to come here, frog!" Arthur said, and Francis, who had been hanging upside down, stood up, with difficulty, and walked over to Arthur's spot on the floor.
Arthur looked at him, blushing, and slowly reached out for him.
When their hands touched, they saw why the level was called rainbow road. Francis saw how bright and beautiful Arthur's green eyes were. And Arthur saw the deep sea-blue of Francis's eyes. And they knew at that moment, they belonged together.
"F-f-Francis...." Arthur blushed.
"We belong together," Francis smiled, and leaned forward, gently kissing the Brit, who blushed bright red, but kissed back.
When Francis pulled away, Arthur simply blushed. "I-I love you, frog."
"Je t'aime aussi, lapin."

(A/N I think I'll end this here. Comment if you want an epilogue or something.)
