When I Know What's Real- couples! (Read the intro!)

I'm having a tough time deciding who should be with who in my story (you should probably read that first). I have the personalities of my OCs here, so read this and decide, please!

Lara- sweet and bubbly.
Erika- likes to tease and crack jokes
Kathy- outgoing and not afraid to smack someone
Chrissie- loud, short temper. Same sense of humor as Erika
Lacy- sweet, considerate, in her early twenties (already gonna be Kakashi)
Sam- motormouth who always seems on a sugar rush
