He's a death angel while she's the angel of happiness and love. He's feeding in fears and sorrow of a person while she feeds in love and happiness every person feel. He walks in the darkness while she walks in light. He wishes that people will die while she wishes an everlasting life for the people. He's living in the harsh world of hell while she's living in the peaceful place in heaven. He seldom betray his team while she always cooperate with her team. He leads every person into darkness while she leads every person to light. He's teaching every person to curse God while she's teaching every person to love Him. He hates everybody while she loves everything. He loves every person weaknesses while she loves every person conquering every problem. He's there to ruin every dream while she's always there to tell God you want your wishes to be granted. He wants life to end up suffering while she wants every person life to end up satisfied and smiling. He's the opposite of her while she's the opposite of him but, when they faith met; they fell in love with each other. They crossed the boundary of hell and heaven to meet each other secretly. How could a devil learned how to love an angel which is his total opposite and how can an angel learn to love someone who hate people and God? It was still a big question mark on how an evil surrendered his horn just to be the match of an angel and how can an angel surrender her wings just to say she loves him with all of her heart? A big question mark for heaven and hell even for Satan and God. Does human can cross any boundaries for love like a demon and an angel did?
