Because in this fanfic Lincoln declared he loves only Lucy because she doesn't make fun of him. All sisters were heartbroken but reacted differently, some were angry and some were sad. People react differently.

Canon division was in "Tents Debate", team beach and team dairyland.

For most of episodes there is a division 1 boy vs 10 girls. All so there would be a conflict for a sake of plot.
