I GOT SHOT!!!! With a water gun....O_O

Angel and Un have been roughing it out for 3 years know ever scents Angel found Un bleeding and crying on the sidewalk by her old home. Angel, 16 years old now is coming from a tough background and ending up living on her own with only Un for company, they finally settle down and try to relax, but what happens when an old love comes back to haunt you and a new one is the biggest jerk/ass you've ever met?
