Muzan was not happy at all after receiving the love letter.

Because these love letters all praised his "beauty," praising his skin as whiter than a woman wearing white powder, and praising his slender figure as delicate as a willow.

Every sentence hit Muzan's sore spots.

Muzan didn't think these people were praising him; instead, he felt they were calling him a sickly weakling.

Muzan's aesthetic sense has become similar to Shugo's, almost as if he was raised by Shugo.

When it comes to male beauty, Muzan admires Shugo's masculine and robust physique, which is full of male hormones.

When sleeping close to Shugo, you can easily feel his strong chest muscles and powerful arms with each rise and fall of his breath.

That's the kind of healthy and strong that Muzan envies and admires.

The head of the Ubuyashiki family seemed to be deep in thought; at least his ten-year-old son hadn't yet developed the sense of love.

"Who made the decision on the marriage?" Muzan asked quietly.

The head of the Ubuyashiki family replied, "It is the head of the Fujiwara family."

Muzan suddenly clenched his right hand into a fist.

"As expected, he still cares," the head of the Ubuyashiki family thought to himself as he glanced at the crowd.

Muzan showed neither joy nor rejection.

He was just puzzled, but after the head of the Ubuyashiki family explained that the reason was that the Fujiwara Kita family wanted to strengthen their ties through marriage, Muzan quickly agreed.

The head of the Ubuyashiki family visited the Fujiwara Kita family and delivered the message.

The head of the Fujiwara family was still worried, so he personally took the initiative to test the waters, inviting Ubuyashiki Tsukihiko over under the guise of a fortune telling.

Muzan's fiancée is named Fujiwara Tomoko, a little girl who is only eleven years old.

Both of them were adults, and it was necessary to maintain proper separation between men and women.

So they met through a screen.

Tomoko spoke softly to her future husband through the screen and layers of curtains.

The maid hiding to the side secretly observed her young mistress's future husband. As she carefully examined his appearance, her face flushed slightly, but she did not notice the impatience and indifference in Muzan's eyes.

After the conversation ended, Muzan hurriedly left.

The maid then came in and whispered what she had seen.

Upon hearing the maid's description of the man's appearance, Tomoko's face lit up with joy, recalling the man's refined manner and demeanor during their earlier conversation.

This seems like a good marriage, Fujiwara Tomoko thought.

After Muzan left, he couldn't wait to see Fujiwara no Shugo.

He understood what the other person meant.

He's an adult now, he can't act like a child and act spoiled towards Shugo anymore, he needs to act like an adult.

Shugo would tolerate his childish whims, but others wouldn't.

In his view, this invitation was a ladder offered by the other party, which he could then use to get down. Besides, he missed the other person.

The bottom line has been lowered without anyone even realizing it!

The stray cat, returning home, purred with joy.

Muzan was already quite familiar with the interior of the Fujiwara Kita family compound, so he walked to Shugo's bedchamber.

Before coming here, he had inquired and learned that Hiraga was off work today.

When Shugo, who was reading official documents in an unseemly manner in his bedchamber, heard the servant report, he was stunned for a moment, then realized something and cursed under his breath.

He ordered someone to bring Muzan in, and Shugo straightened his posture, adjusting to guest mode.

He also has an image to maintain.

When Muzan entered, he saw Fujiwara Shugo standing tall and straight like a green mountain.

The two were already very familiar with each other, so Shugo stopped beating around the bush and asked directly.

"What brings you here?"

The overly straightforward question provoked Muzan, who was swallowing his grievances, to explode.

"Can't I come over if I have nothing to do?"

Shugo looked completely bewildered, not understanding why Muzan was angry at all, and quickly apologized to calm him down and talk.

Kibutsuji Muzan, a cat with an unpredictable temper.

After the person apologized, Muzan calmed down and began to speak normally.

"Engaged?" Shugo almost choked on his tea. When did his own cabbage get eaten by a pig?

Fujiwara Shugo thought of the official Muzan guidebook, which showed that Muzan had married five wives during the Heian period, and that these five unfortunate women all committed suicide because of his harsh and insulting words. His eye twitched.

However, he probably knows who was behind Muzan's arranged marriage.

Upon realizing that his information had been blocked, Shugo's expression darkened, and he cursed his cheap father inwardly for acting on his own initiative.

Muzan asked in confusion, "Didn't you know I was engaged?"

Shugo shook his head and said it was arranged by his father.

"Which noble lady has Father arranged for you?" Hiiragi asked, sounding like an old father scouting a potential wife for his son.

Muzan described Fujiwara Tomoko.

Hiiragi tried hard to recall, but he didn't remember anyone from a collateral branch of the clan.

"Do you... want this engagement? If you don't like it, I'll find a way to annul it." Shugo carefully said these words, which could be considered as rescuing the little girl named Tomoko.

Shugo didn't intend to explain the inside story. Muzan, who was only a teenager, was still a child. There was no need for him to understand the adult world so early.

"You don't like me having this marriage agreement?" Muzan asked.

The parent, who had been racking his brains to stop his beautiful young daughter from falling in love too early, choked up and said gently, "...It's not that, it's just that I feel you're not ready yet. Perhaps one day you'll meet the love of your life? This engagement will then become an obstacle..."

"A lover I want to spend my life with?" Muzan repeated softly, his eyes filled with confusion. What was that?

Muzan thought so, and he asked so.

Hiiragi:……

Muzan tried to give examples from people around him: his father? If he spent his whole life with that hypocritical old man, he would definitely kill him. His siblings? Ha, would they just ostracize and isolate him their whole lives?

If he had to name someone he wanted to spend his life with, Muzan could only think of Shuuga.

Being with Shugo is the most comfortable thing!

Muzan spoke the truth frankly.

Shugo: ...You can't say that!

"Muzan, haven't you tried to make friends with other people?" After thinking about Muzan's social circle repeatedly, Shugo had to admit that Muzan had no friends at all!

However, the head of the Ubuyashiki family should have introduced Muzan to some of his connections.

"He asked me to go, but I went a few times and got bored, so I didn't want to go anymore," Muzan answered frankly.

Hiiragi: ...You ungrateful second-generation rich kid

The elderly father, Shugo, had to give Muzan some advice: he should socialize well and not become autistic.

The true old father, the head of the Ubuyashiki family: ...
