After agreeing to meet Reiko Akiba at the Teitan music classroom at 2 PM the next day, Kusunoki Hanyu accompanied the group who had just finished watching the rehearsal as they slowly walked out of the concert hall.

Ran, Akemi, and Sonoko walked ahead, chattering excitedly about the rehearsal they had just finished.

Yuzuru and Ai strolled leisurely to the very back of the group.

As they walked, Ai, who had been silent and lost in thought, suddenly said in a voice only the two of them could hear: "So, you're not interested in the concert itself, but rather in a particular person at the concert."

When the cunning little girl realized his intentions, Yuu Nan calmly changed the subject, saying, "Ai, don't you think Miss Akiba is a lot like you?"

"Hmm?" Ai was slightly taken aback, the little girl asked in confusion, "How does it resemble me?"

Yuzuru smiled slightly and said unhurriedly, "Equally beautiful, equally talented in their respective fields, and equally the tsundere queen type who's tough on the outside but soft on the inside~"

As soon as he finished speaking, a cold gaze came from the side.

After giving Yuzuru a deathly glare filled with murderous intent, Ai was about to refute what Yuzuru had said, but after thinking about it carefully, she found that she couldn't find a way to refute him.

Damn, what he said makes so much sense.

"snort!"

The haughty little girl snorted coldly, ignoring Yuzuru Nan, and quickly chased after her older sister.

Yuzuru smiled as he watched Ai's retreating figure and quickened his pace to catch up.

They came out so early not just to watch the concert rehearsal, but also to play volleyball in the park later. Xiaolan played with Yuanzi the day before yesterday and is now really into it.

Later, I'll also visit the Yuanzi dumpling shop at the Mihua Municipal Center. The shop is all renovated, and now we're just waiting for the employees to arrive after their intensive training so we can open for business.

Another leisurely and pleasant day.

...

The following day, July 10th, the sky was clear and the sun was shining brightly.

Hmm, is something wrong?

Hanyu Nan, who was sitting in the living room early in the morning, waiting for the maid to prepare breakfast, twirled a gray flute in his hand and looked at the weather forecast on TV with some surprise.

That's not right. If he remembers correctly, yesterday was July 9th, and today could be October 7th or September 7th, but it shouldn't be July 10th.

It didn't skip a time, amazing!

"Is this a new prop you made?"

Just as someone was complaining about this bizarre timeline, Ai, who was carrying a baby coming downstairs, silently walked up to him, stared at the gray flute with a Doraemon drawn on it in his hand, and asked softly.

"Yes, I just made it this morning." Yuzuru reached out and caught the little Eevee that pounced on him, and introduced it: "It's called the Inverted Magic Flute."

"The Upside-Down Magic Flute?" Ai tilted her head slightly, thinking for a moment, and asked, "How is it upside down? Does it make people go from washing their hair standing up to washing their hair upside down?"

"You'll see once you try." Yuzuru picked up the Inverted Magic Flute, a malicious smile creeping across his face. "Ai, what are you thinking right now?"

Seeing the man's wickedly humorous expression, Ai knew she was doomed and destined to become another guinea pig for the new gadget. She gritted her teeth and said viciously, each word distinct: "I...want...to...bite...you...to...death!"

No, you don't want to.

Yuzuru put the inverted magic flute to his lips and gently blew it. A melodious flute tune, carrying a mysterious magic, landed precisely in Ai's ears as she was grinding her teeth.

The next second,

Ai's expression changed from gritting her teeth to beaming with joy in an instant. "Good morning, Yuzuru-nii! Good morning, good morning!"

"That's more like it!"

Yuzuru smiled smugly, removed the inverted flute from his lips, and the melodious flute music disappeared.

The next second,

"Yu! Sheng! Nan! I'll bite you to death!"

Ai's eyes blazed with fury as she opened her gaping maw in a rage.

"Ding ding dong~ ding ding dong~"

The melodious sound of the flute rang out again.

Ai, her eyes blazing with anger, instantly softened into a sweet, coquettish voice: "Brother Yuzuru, please let me...~"

...

...

When the little maid came out of the kitchen after making breakfast, she immediately saw her younger sister sitting to the side, her chubby cheeks puffed out in a huff, fiddling with a flute in her hand.

Meanwhile, Yuzuru looked completely satisfied, rubbing his damp cheeks.

The Inverted Flute—by playing a song with it, one can make any person or creature that hears the flute do the exact opposite of what they originally intended.

For example, a vicious robber who originally only wanted to steal money might become willing to hand over all his money to the victim when he hears the sound of the inverted magic flute.

The urge to curse becomes the urge to praise, the urge to kill becomes the urge to save; all original thoughts and intentions are completely reversed, hence the name "The Flute of Inversion".

That's why when Ai hears the sound of the flute, she goes from wanting to bite Hanyu Kusunoki to wanting to kiss him.

The only drawback is that you have to keep playing the inverted magic flute continuously, and the sound of the flute cannot be stopped even for a moment, otherwise the target person or creature will quickly recover.
