Muzan's fourth day of recuperation:

Surprisingly, Youcan was a quiet, introverted, and well-behaved child.

He was a completely different person from the boss who later criticized everything and everyone.

The things that kids this age like, Muzan also likes.

……

Muzan's fourth day of recuperation:

Little Muzan is a rather eccentric child who will never tell you directly what he wants; you have to figure out what he wants to do yourself.

Otherwise, Muzan will look at you very unhappily, his lips will be pursed into a straight line, and he might even ignore you.

It's like a cat with its butt facing you.

Moreover, Muzan wants to have everything that others have, regardless of whether it's actually useful or not, such as football.

……

"What did I do to offend you again?" Shugo asked helplessly, looking at the indifferent child.

The child avoided his gaze and remained silent.

Shugo turned around and asked the servants who were with Muzan what had happened.

The servants listed in detail what had happened that day, including Agu coming over to show off his birthday presents.

Shugo frowned, a strange look flashing across his face, and his gaze drifted to Muzan.

Is this because they're jealous that Agu got a gift?

Not talking is a bad habit; let me help you change it.

At lunchtime, plates of food were laid out on the table, unlike the usual practice of serving individual portions.

Hiiragi broke the rule of not talking while eating and amused the child with a smile.

"Say what you want, don't keep everything to yourself."

Hiiragi pointed at the kitten dumpling.

This is one of Muzan's favorite foods.

Which one do you like? The black one? The orange one?

Muzan's gaze drifted between the buns of different colors.

Seeing this, Hiiragi opened his blood-red mouth as if to stuff the orange cat bun into it.

"Orange."

Muzan's cat-like eyes widened, and he hurriedly exclaimed, "Orange!"

Children all love sweets.

In Heian-kyo, even for nobles, sweets were not something they could eat anytime.

Looking at Muzan chewing on a cat-shaped bun, Shugo rubbed his head.

"Next time, just say what you want."

"I'll also give you a Renguang item on your birthday."

……

Muzan recuperates for 6 days:

Muzan must be the type of patient doctors dislike the most, or rather, child patients are always difficult to deal with.

He did not follow the doctor's advice.

"Young master, you can't eat anymore!" The servant put on a smile that looked more like a grimace, trying his best to coax the child.

Eating snacks instead of regular meals is a common problem among children.

Muzan pushed away the rice porridge, which contained an unknown amount of medicinal herbs, with disgust, and ate the pretty and delicious sugar balls, with sugar frosting falling down in tiny specks.

He felt better and didn't need to eat that awful porridge anymore.

“No, take these away,” the child said imperiously.

Hiiragi, who was summoned: ...

"No."

“You said I should say what I want. I want candy!” Muzan retorted, using the words he had taught him at noon.

“You can say that it’s my business whether I give it to you or not,” Shugo smiled.

Muzan's eyes widened, his gaze seemingly saying, 'How could you do this!'

"That's not right," the child exclaimed hastily.

Muzan was not fooled by the cunning adult.

"You can only eat one piece of candy a day. If you eat too much, worms will crawl into your teeth, make holes in them, and cause you so much pain that you can never eat candy again."

Terrified by Shugo's horrifying words, Muzan obediently handed over his candy.

Hiiragi (proudly): No kitten can escape the clutches of a human.

……

Day N of Muzan's recovery:

Fearing that Muzan would fall behind, I personally taught him to recognize characters and read. The strategy of using storytelling to motivate children to learn was very successful.

Muzan learned very quickly and also enjoyed the story of Hyakkimaru fighting the demon god.

As they grew closer, Muzan subtly tested my limits and my tolerance for him, even learning to act coquettishly.

"I want it." Muzan pointed to the red magatama that Shugo was wearing.

Hiiragi raised an eyebrow.

He didn't care about the accessory, but he also didn't want the child to get it so easily.

"If you can write out all the characters I taught you, I will give them to you."

Muzan fell silent.

Over the past few days, I have taught most of the commonly used characters.

It would be too difficult to get a three-year-old to go through the whole process from beginning to end.

A stubborn child never admits defeat.

After studying for several days, Muzan successfully took the magatama from Shugo.

……

Muzan's first day of school:

The dietary therapy had some effect, and Muzan was able to go back to school.

The teacher commented that Muzan was quite smart, smarter than my silly, stupid younger brother.

However, Muzan, who dressed like a girl, was ostracized.

I made him change his clothes and even called Agu over to give him a lecture.

The situation has improved.

However, Muzan still hasn't made any friends, and seems to disdain making friends.

"Who wants to be friends with them?" Muzan pouted unhappily, then added, looking at Shuugo's expression.

"I don't make friends with idiots." That's not the real reason.

Those people could never be my friends.

Fujiwara Shugo's excessive attention to Muzan was the root cause of the conflict between the two.

Muzan thought smugly, "You want Shugo to come back and care about you? Impossible!"

……

Muzan's Xth day of school:

Agu clashed with Muzan, and he deliberately kicked a kemari ball at Muzan, the ball whistling past his ear.

Muzan was so frightened that he fainted on the spot and developed a high fever that night.

What the hell!

Has their relationship reached this point?

How do those pet owners who have both cats and dogs manage to do it? I've tried my best to treat them equally!

……

Shugo gave Agu a severe scolding and ordered him to apologize after Muzan recovered from his illness.

Agu knelt to the side, watching the busy crowd. His brother's face was as cold as ice. The heavy atmosphere made Agu belatedly feel afraid.

“Brother…” Agu murmured, seeking comfort.

Shugo didn't say anything, but just glanced at the child indifferently.

Agu fell silent.

The head of the Fujiwara Hoku family was also present.

The fact that someone from the Fujiwara Kita family killed a three-year-old child is an outrageous scandal!

If word gets out, Agu's reputation and future will be ruined.

With fame comes trouble, and the Fujiwara Hokuke family, now in a high position, naturally had no shortage of people who wanted to bring them down.

Looking at the child being rescued, the head of the Fujiwara family showed no emotion.

This is the scene that Ren Guang saw when he arrived carrying a can of strong liquor.

"You brought the supplies? Do as I say." Shugo glanced at Jinko and quickly gave instructions to the doctors.

The doctors obeyed orders without question.

Over the past three years, Shugo has been studying and discussing with these physicians supported by the Fujiwara Hokuke family, and has long since won them over.

In an era when medical knowledge was still limited and associated with demons, ghosts, witchcraft, and exorcism, even a little bit of common sense about hygiene from later generations was enough to impress these doctors.

Except for that one outrageous doctor who turns people into ghosts.
