A unique physics lesson has come to an end.

Yuzuru Hanyu emerged from the laboratory with light, quick steps. His eyes were clear, and he exuded a refreshing aura.

Now is the time for saints.

As for the certain genius young scientist, under the painstaking guidance of her "competent" teacher, Nanami Hanyu, who devoted a great deal of effort to teaching her with various vivid and interesting examples and unique teaching methods, she finally grasped the unique physical charm of "friction".

After all, everyone has their own area of ​​expertise.

Shiho's expertise is concentrated in biology and chemistry, so it is entirely understandable that she lacks knowledge of physics.

Fortunately, she had Yuzuru Hanyu, a "physics teacher" with solid professional knowledge, who could always teach her obscure physics knowledge in an easy-to-understand way.

And it's free!

...

Dinner was ready quickly.

To celebrate her young master's victory in the competition today, Akemi, for the first time ever, allowed Ai to drink a small, intoxicating beverage using the drunken bottle cap.

Previously, because a certain little girl accidentally drank too much with a bottle cap and stumbled into someone's room in the middle of the night, startling Akemi who was in her prime, the little maid forbade her sister from drinking any more.

Even the bottle caps that were still intoxicating were confiscated.

She only allowed her younger sister to have a small cup when there was something happy happening at home.

"cheers!"

A crisp sound rang out in the restaurant as the family of four—Hanyu, Akemi, Ran, and Ai—raised their glasses and gently clinked them together. At that moment, the scent of happiness filled the air.

After Shiho drank that small cup of beverage, a faint blush appeared on her originally cool cheeks, making her look even more charming.

She sat there quietly, enjoying the pleasant feeling of being slightly tipsy, listening to everyone chatting. The corners of her mouth unconsciously turned up slightly, and her eyes were full of tenderness and satisfaction.

After the meal, Mingmei and Xiaolan cleaned up the dishes.

Yuzuru accompanied the slightly tipsy Ai as they slowly walked into the living room and sat down.

Ai leaned back on the soft sofa, her eyes slightly dazed. A new movie was playing on the TV, but Yuzuru seemed to be teasing her, casually reaching out and scratching her soft belly.

After a token resistance, the little girl, outmatched in strength, had no choice but to give up and let him be.

Nestled in Yuzuru Nan's arms, Ai gently nuzzled her head, as if searching for the most comfortable spot. A nonsensical movie was playing on the TV, its colorful lights shimmering on their faces.

Ai's fingers unconsciously tugged at the corner of Hanyu Nan's clothes, and she suddenly asked, "Are we going to Osaka next week?"

"Well, after my kendo competition ends, the Satsuki Cup karuta tournament that Kazuha will be participating in will start. After the competition, our family can go and enjoy the autumn leaves together. Just thinking about it makes me feel wonderful."

Hanyu Nanami casually rested his chin on his hand and announced his plans.

These are all plans that have been prepared in advance, and if nothing unexpected happens, it should be very lively.

The little girl nestled obediently in his arms and nodded. Then, as if she had thought of something, her icy blue eyes narrowed slightly: "Who are the family members you mentioned?"

The devil is in the details.

As a scientist, focusing on the key points is her specialty.

Yuzuru paused in his mischievous hand, then said naturally, "Of course it's our lovely Ai, Sonoko, Ran, Akemi, Ayako-nee and Reiko. It's a family, so of course we should all be together."

As he spoke, he gently tapped Ai's nose with his finger, as if soothing a sensitive little animal.

As for Kazuha, she's in Osaka.

"Neat and tidy?"

The cunning little girl gave him a playful look. "Are you sure that's all? What about all your other beauties? Aren't you going to call them along too?"

Regarding her playboy's extramarital affairs.

As sensitive as Ai Haibara is, she probably knows the most about this.

Having been by Yuzuru Nan's side for so long, how could she not notice those ambiguous feelings hidden in the shadows?

"Cough cough..."

When his true purpose was revealed, Yuzuru's expression instantly turned embarrassed, but he immediately began to retaliate, reaching out to gently pinch Ai's nose, "What, is Ai jealous? Don't worry, you are unique and irreplaceable in my heart."

"Stop being silly, I won't be jealous."

Xiao Ai rolled her eyes at him, feigning disgust.

But her slightly reddened ears seemed to betray her, quietly revealing her true inner emotions.

After calming her wildly beating heart, she swatted away the large hand that was still playing tricks on her lower abdomen and haughtily snorted, "Invite whoever you want, I don't care!"

Although the little girl said that, her body betrayed her by snuggling closer to Yuzuru's chest, as if silently asserting her dominance.

Jealousy is one thing.

But she also knew that her young master loved beautiful women.

So, as long as it doesn't affect her and her sister's standing in someone's heart, Ai doesn't mind considering his feelings.

After all, she knew in her heart that some things were beyond change, so she might as well turn a blind eye and be content as long as her place in his heart was irreplaceable.

"Since it's a family outing, remember to invite everyone you should, so you don't forget any of the beautiful ladies and then have to run off to apologize afterwards."

"No, I'm prepared."

Yuzuru instinctively replied, but immediately regretted it.

When she realized what was happening, she met Ai's ambiguous smile, as if to say, "See? I knew you had something to hide."

It exposed...

However, he still had to make an excuse. He coughed lightly, trying to cover up his embarrassment, and said in a serious tone, "Ai, what I mean is that I have already invited Reiko and Ayako. Don't misunderstand."

"cut!"

Ai didn't believe it at all, and glanced at Yuzuru with disdain.

She suddenly blurted out, "You are not allowed to invite Vermouth!"

Anyone is fine, except that bad woman.

Ai still vividly remembers the time in the villa garage when Vermouth pinned her down in the car seat and bullied her, leaving her covered in dirt.

This is an absolute disgrace!

She, a brilliant and beautiful young woman, had never suffered such humiliation.

Yuzuru Hanyu would definitely not agree to this request!

The solution is, of course, quite simple.

"What are you doing..." Noticing the gaze above her gradually becoming strange, Ai's expression changed. Guessing that Yuzuru was going to cheat, she got up and tried to run away.
