Su Cha is a little ghost. No one cares for him or loves him, and when he opens his eyes, he's in a graveyard.
He drinks rainwater when he's thirsty and eats resentful spirits when he's hungry. Looking at the happy family in his tattered picture book, he lives a miserable life.
One day, a handsome young man comes looking for him.
He picks up the bouncy little ghost and gives him a shake. "I'm your guardian."
Su Cha follows the man home and discovers a gorgeous long-haired beauty, as well as an older brother and sister who don't like to talk.
It's just like the happy family in his picture book!
Su Cha: Mommy, Daddy, big brother, big sister, I'm here!
A family life is irresistible to the lonely little ghost. He doesn't mind that his mother is an underpaid neighborhood-office worker, his father is unemployed, and his older siblings are illiterate and often fight.
At the supermarket, Su Cha turns into a little kid and thoughtfully points to the cheapest formula. "Mommy, I just want this one. It's the cheapest!"
When he catches his father fighting someone in the street, Su Cha rushes over to stop him. "Stop fighting! We can't afford to pay for this!"
The two adults look conflicted. "..."
To teach his older siblings to read, Su Cha starts from the very beginning.
Su Cha: Big brother, big sister, repeat after me: a, o, e, i, u, v!
His older siblings, covered in blood from a fight, their fangs still out: "..."
The well-behaved little Su Cha successfully moves up to the junior kindergarten class.
He loves being clean and is polite. He stands behind his parents and siblings, greeting his classmates, but they all scatter like frightened birds and beasts, wailing.
Classmates: Waaah! Waaah! Teacher, he's so scary!
Su Cha: QAQ
His parents take him to a new school. The classmates there are even weirder than before. Some have horns, and some have tails.
But Su Cha is a good kid and treats every classmate politely. He helps his horned classmates care for their horns, washes and brushes his classmates' tails, ties them into little braids, and sticks on tiny rhinestones.
Everyone is afraid of the boy in the corner, so Su Cha thinks it over and takes out some little cookies baked at home.
Su Cha: Big brother, would you like to share some cookies with me?
The boy has red eyes and scales on his face, and his expression is icy as he looks up at him.
Su Cha nervously bites his finger. "It's okay if you eat them all."
The Special Abilities Bureau receives a tricky assignment.
A monster prophesied to destroy the world has emerged. Something has gone wrong, and its mental age is only that of a child.
The director overrules the objections of everyone else, takes the little monster home, and tries to find an effective way to deal with it.
To that end, the Special Abilities Bureau sends the director and the team captain, and even dispatches an ancient ferocious beast that has been brought under their control.
When no news comes for a long time, everyone at the Bureau grows uneasy and can't help going to the director's house.
They don't see any bloody carnage. All they see is a fair-skinned, adorable little boy standing on tiptoe to mix himself a bottle of formula.
The monster, now a little boy, is polite and well-behaved. He speaks to them through the security door: "Mommy and Daddy aren't home. I have to go to school this afternoon."
Everyone: He's kind of cute, actually. I'm swooning!
Is this well-behaved little kid who goes to school and even gets gold-star stickers really the world-destroying BOSS from the prophecy?
