Everyone in the Three Realms knows that Michael, the Heavenly Court's consort prince, conquered half the Three Realms with his looks and has a scandalous love life that has left affairs blooming everywhere. He has three children.
His eldest daughter, Luna, is the current ruler of the Hall of Li Huo. Her birth mother is unknown, and she is an angel through and through.
His second son, Haniya, is the embodiment of divine beauty and wielder of the power of light. His birth mother is Metatron, and he is the Heavenly Kingdom's beloved little prince.
His youngest son, Cyrill, is the little prince of the Red Sea and heir to the vampire clan. His father is Lofis, and everyone calls him the Three Realms' number-one nepo baby.
But only Michael himself knows that he has another child.
An angel he refuses to acknowledge, abandoned by fate.
An angel whose veins carry both his blood and that of the Lord of Hell.
Cassius grew up on the streets, stumbling through life for thousands of years thanks to the kindness of other angels. The biggest stroke of luck in his life was being selected by the Morning Star Palace and becoming one of the attendants serving the holy son, Messiah.
But when he arrived at the Morning Star Palace and looked at the holy son Messiah's face, which bore an eight-out-of-ten resemblance to his own, Cassius belatedly realized:
Oh. He seemed to be the illegitimate child of the holy son before him, a man said to devote himself wholeheartedly to God and never indulge in the seven emotions and six desires.
And from Prince Gabriel, who loved gossip and digging up the secrets of his colleagues, Cassius learned something else.
Apparently, he was also a little bit related to Prince Michael, who lived just one wall away from the Morning Star Palace.
Michael had once faked his own death to secretly give birth to the child who should never have come into the world, then personally pushed him into Hell.
Later, he brought that child back to his side.
After falling into Hell, Michael, the current consort prince of the Heavenly Kingdom, became the taboo of the Demon King, a fact known to every demon and fallen angel.
Mention him, and you die. That's how bad it was.
But a rumor began circulating in Heaven:
The holy son Messiah, whose appearance was identical to Lucifer's back in the day and who took up residence in the Morning Star Palace after the War of the Morning Star, was merely a substitute kept by the consort prince.
The two angels had even secretly had a child, whom they were raising in the Morning Star Palace.
The demons trembled in fear.jpg
Damn it, some angel was reckless enough to find a substitute for their boss, but could they please not drag them all into it and get them killed too?
Until one day, the illegitimate child said to belong to Michael and Messiah appeared in Hell.
The Satans stared at one another.
That bloodline aura seemed... a tiny bit familiar?
[Bonus Scene]
Michael never imagined that Lucifer would find out he had secretly hidden a child in Heaven.
He had clearly prepared three layers of cover stories:
A young attendant at the Morning Star Palace;
Messiah's illegitimate child;
His and Messiah's child.
But the moment he turned away, his precious baby was already in Rodeoga.
Michael: ...
Lucifer: If you want the baby, trade yourself for him.

Notes:
1. A fake-death-and-runaway-with-the-baby story. It's an old-school trope, but I still want to write it.
2. The background has been changed from Love Affairs. Mimi always knew the little one existed, he just never acknowledged him.
Theme: When life gives you a broken jar, you can do more than smash it. You can keep using it while it's broken.
