Ye Nao is a little System with ugly code and a bit of a dopey personality. The other Systems often make fun of him.
Later, the little System retires and accidentally binds to a human child's body in the human world.
He gets unlucky: the body he's bound to is very weak and sickly, and often needs shots and medicine.
Unable to tell what is beautiful or ugly, he looks at the soft little face reflected in his bowl of medicine and is bewildered. He still thinks he's the ugly System that everyone hates.

Because he thinks he's ugly and unlikable, Ye Nao likes to shut himself away at home.
Worried that Ye Nao will grow up unable to fit in, his mother, a movie star, takes him by the hand and brings him onto a parenting variety show.
Facing the camera, Ye Nao asks curiously, "What is this?"
His mother says gently, "It's something that lets your big brothers and sisters see Nao Nao."
But when Ye Nao hears this, he bursts into tears on the spot. "I'm an ugly monster. I don't want everyone to see me!"
The audience watches this adorable little baby, with rosy lips and pearly teeth, sobbing and saying he's an ugly monster, and they're stunned.
Whose little darling has such a poor sense of self-image?!

Ye Nao worries that nobody will like an ugly monster on the show.
But later, he discovers that when he gets sick, all the children gather around to comfort him and wish him a speedy recovery.
The big brother who looks fierce is actually a little tsundere. He says he doesn't care, but when Ye Nao has a fever, he stays by his side all night.
It's so nice. Nobody here dislikes him for being an ugly monster.

In his previous life, Xi Lian was bullied on a parenting variety show, with the naughty kid Ye Nao leading the way. It left him with a huge childhood trauma.
Now that he's been reborn, he decides to make that little brat pay for every humiliation he suffered.
But when he accidentally scrapes himself, Ye Nao says with concern, "Does it hurt, big brother? I'll blow on it for you."
When he's hungry, Ye Nao carefully takes out his most precious candy and offers it to him. "Big brother, have some yummy candy!"
Every time Xi Lian thinks about getting revenge, he tells himself to wait a little longer. Just a little longer.
Ye Nao is so frail that if Xi Lian forgets to close the window, Ye Nao will come down with a serious illness.
There'll be plenty of time to get revenge later.
Later on, Ye Nao becomes the beloved darling of the show, a sweet, well-behaved little dumpling that everyone loves.
Xi Lian especially treats him like a little bodyguard, cherishing Ye Nao with all his heart and not letting anyone touch him.
In winter, he helps Ye Nao put on his little socks. When Ye Nao is sick, he feeds him medicine one spoonful at a time and strokes his head, telling him to get better soon.
More than ten years pass, and Ye Nao still thinks of Xi Lian as the best friend in the world.
But Ye Nao doesn't know that the way Xi Lian looks at the friend he cherishes is slowly changing.
