Well, I've decided on the names, Cygnus is the main character, Haze is the girl that kills herself and whatnot, and Squall is the "bad guy."
Cygnus will confront Squall when he hears the news about Haze, and will lose their fight, vowing revenge and whatnot.
After Cygnus' revenge plan is carried out, Squall comes to him for help, thinking he's going crazy. Cygnus realizes he's a monster and whatnot now, and Squall dies in his care.
I'm still not sure how it's gonna end, either with the above bullet, or he determines to make things right and does that somehow
