Yu Yu is a seasoned little one from the Quick Transmigration Bureau. He drinks the tastiest milk, turns on the most irresistible charm, and is doted on wherever he goes.
Before he left the Quick Transmigration Bureau to return to his original world, his coworkers gently reminded him, "Good little one, we've arranged a happy family for you. You'll have a powerful dad, a gentle mom, a clever big brother, and a kind big sister. All you have to do is drink your milk and grow up well."
Yu Yu hugged his bottle and nodded seriously. "I'll drink five bottles a day!"
Then Yu Yu returned to the post-apocalyptic world and reunited with his family.
The apocalypse was cruel. Monsters roamed everywhere, and life was hard.
His family couldn't afford formula, so Yu Yu had to drink beast milk his father risked his life to get.
They didn't have money for school, so Yu Yu had to learn to sing from his mother, so he could make a living later.
His older brother's leg was injured, so he could only take online gigs to earn pocket money and buy Yu Yu candy.
His older sister went out to fight in underground boxing matches. Sometimes she was gone for a long time, and when she returned, she was covered in injuries.
Yu Yu knew his family was working so hard for him, so he drank his milk with even more determination, hoping to grow up quickly and protect them.
But before he could grow up, the end of the world arrived.

When the System assigned to Yu Yu returned from vacation, it discovered that Yu Yu's world was on the verge of collapse.
The System rushed over to investigate, but ran into the family members originally assigned to Yu Yu. That's when it learned they had never even met him and had gone mad searching for their little one.
The System pinpointed Yu Yu's location. He was actually at the center of the world's collapse! Everyone hurried over, expecting the worst, only to see
On a sunny meadow, Yu Yu was sprawled across the lap of some indescribable great demon, looking woozy and possibly drunk on milk.
The undead witch who had once nearly wiped out the church murmured a sleep blessing in his ear, her gaze incredibly tender.
Not far away, a genius hacker and an interstellar empress were discussing how to finish dismantling the old world and rebuilding a new one before the little one woke up. They were locked in a heated argument over whether the new world should be full of milk or candy.
The System: "Um..."

The System: "Dear villainous powerhouses, may I ask why you want to destroy the world?"
The great demon: "Oh, Yu Yu said he wants to be the pillar of the family when he grows up. I don't want him to have such a hard life, so I'm creating an easier world for him."
The undead witch: "I taught Yu Yu to cast death incantations, but all he can do is blow bubbles. I was afraid he wouldn't be able to protect himself if he ran into danger, so I had to eliminate every danger in advance."
The genius hacker: "Mm, I thought the same thing."
The empress shrugged. "I conquered more than a dozen planets for Yu Yu to choose from. He said he still liked this one best. What can you do?"
"And you?" The System looked at Yu Yu's monster friends.
The monsters: "Because he's cute~"
