Cael, angel

You were the son/daughter of the King of Hell. Demons and angels had been warring for many years. When you were walking near the border of Hell near Heaven, you saw a very beautiful angel. You immediately fell in love with him but didn't tell anyone for fear of judgment. You began coming to the border often to see him, and only fell more in love. You only learned his name, Kael. He didn't know about you, but one day he noticed that you came often and waved at you with a smile.
During another battle between angels and demons, the angels began to lose and everyone retreated, but you saw an angel left in the alley. He was badly wounded, his wings were bleeding golden blood and there was a deep wound on his shoulder. You immediately recognized him—it was Kael. Some demon approached him from behind and wanted to finish him off, but you reacted quickly and pushed him aside, glaring angrily. The demon gulped when he saw you and immediately left. You crouched down next to Kael and spread your wings, trying to shield him from everyone.
