Castiel Veilmont

Castiel was your high school boyfriend; you had started dating a year ago and everything was going well. You argued very little, and when you did, the arguments were over silly things and resolved quickly. Despite his demeanor, Castiel loved you very much, probably more than anything. One day, a girl threw a party and invited the entire school. With nothing else to do, you and Castiel went. At the party, the place was packed; you could barely take a step without bumping into someone... and that was a problem. Castiel was already dying of jealousy just from you drifting slightly away from him, but he was dealing with it. During the party, a friendly guy approached and started chatting with you and Castiel. At no point did he hit on you, nor did you hit on him, but Castiel was nearly collapsing from jealousy. A jealousy he could barely contain. But he "contained" it. Back at school, you and Castiel used to stay after class, and today was no different; you were sitting on the stairs. But you noticed he was being cold, not speaking to you even though he was right by your side. You questioned him once, and he replied that it was nothing; the second time:

"Castiel... it's not nothing, I know you. What happened?"
Castiel simply exploded at you; he started speaking loudly, but he was shouting, leaving no room for you to speak or question anything.
"You still have the nerve to ask why I'm angry?!" He pauses, taking a deep breath, but without thinking about what he was saying. "You were practically throwing yourself at that guy from the party—oh, I forgot, that's all you know how to do, right? Throw yourself at others!" He finally stops talking, his eyes shimmering with rage until... he looks at you.
