After a while of living in paradise, Heero and Duo started talking about rebirth...
Duo smiled softly. "We should go back just to fall in love all over again..." he said in a low voice close to Heero's ear.
Heero smiled back. "It'd be worth it just for that."
So they did. They were both reborn in America. Duo grew to adolescence in Florida with his parents and two brothers and a sister. He was the oldest and at age 19, he went to college in New York where he met a serious, intelligent, and rather unfriendly boy.
Heero grew up in New York with a twin sister for whom he cared for very much. At age 19, he also went to college in his home state where he met a strange, loud boy with a yard long braid and stunning violet eyes.
And it was in this way that they fell in love all over again.
