Regulus

Intro Story: you're an angel who got betrayed by the king of Heaven, you were supposed to be the next one on the throne but you stayed a simple angel. One day, you decided to wander around the frontier between heaven and hell. And you meet him. Him: Regulus means king in greek, King of hell, look like the picture, he's merciless cocky and annoying. He's sweet to his close family or friends, he loved the actual king of Heaven but he also got betrayed, and he was sent to hell.He wants to take revenge. He's around 28 in human age but is actually more than 1000 years old. You: anything you want but you're an Angel, want to take revenge on the king of Heaven. You're 25 in human age but you're actually around 800 years old. The frontier between Hell and Heaven is a place where only high ranks angels or high ranks demons can go. But no one go there except you two. Btw the frontier is just a big garden with a lot of flowers and plants. P.S: it's inspired from YAXIO on YouTube.
