Sister Yun is shy, Yuto Saito is joking?

Yuto Saito looked at Wu Shenmao and Qinqin and waved them off. "Go on, and if you run into any more zombies, bring them here."

Wu Shenmao bowed respectfully. "Thank you, brother."

Though Wu Shenmao was three years older than Yuto Saito, he felt compelled to call him "brother" out of respect for his strength.

Qinqin chimed in with gratitude. "Thank you, brother. Thank you, sister. We'll be heading back now."

The two quickly left. This time, they safely returned to their rented house without encountering any more zombies.

Back in the supermarket, Yuto Saito resumed collecting supplies. There were only a few shelves left in the front area, and he'd be done soon.

Yun Yun walked up to him, her eyes softening as she looked at him. "Yuto Saito, your flying knife technique is really impressive."

Yuto Saito smiled. "It's decent. But Sister Yun, I have other abilities too."

Yun Yun playfully scolded him, "Why do you keep calling me sister? Are you implying that I'm old?"

Yuto Saito chuckled. "If I don't call you sister, should I call you my wife?"

Yun Yun's face turned bright red, her shyness taking over.

Ni Shuang and Natto were taken aback by the exchange, both smiling in surprise.

Ni Shuang teased, "Good one, Yuto Saito! I thought you were just calling her sister out of respect, but you had a plan all along."

Indeed, Yuto Saito had deliberately called Yun Yun "Sister Yun," knowing she would question it, allowing him to flirt with her naturally.

Natto clapped her hands in admiration. "I've learned something new today."

Ni Shuang laughed, "Oh? And what exactly did you learn?"

Natto replied earnestly, "On the surface, Yuto Saito calls her 'sister,' but he's actually using it as a way to deepen their relationship. Just like how you call him 'Xiaotutu' to spark conversations."

Ni Shuang coughed, slightly embarrassed. "You're too clever, Natto."

Natto beamed with pride. "I've always been smart! But Xiaoshuang, why does your tone sound a bit... tea-like?"

Ni Shuang playfully swatted Natto's arm. "What are you talking about?"

Natto pretended to wince in pain. "Ouch, that hurt! Xiaoshuang, you're so strong now, can you be gentler? That really hurt!"

Ni Shuang quickly apologized. "Oh no, I'm sorry! Are you okay?"

Natto grinned mischievously. "Haha, I tricked you! It didn't hurt at all."

Ni Shuang huffed. "Alright, you little liar."

Natto stuck out her tongue, looking both playful and cute. "Women in love are such fools. You didn't catch on to any of my tricks, big dummy!"

Ni Shuang shook her head, half laughing, half exasperated. "You're getting cheekier by the day, Natto."

Yuto Saito watched the playful banter between the two girls with a smile. The scene felt warm and comforting.

He glanced over at Yun Yun, who still had a rosy blush on her face.

Their eyes met, and Yun Yun's heartbeat quickened. Feeling flustered, she mumbled, "I'm going to the bathroom."

With that, she hurried off, her hips swaying as she walked.

Ni Shuang quickly followed. "I'll go too."

Natto added, "Let's all go together."

One after another, the three girls headed to the bathroom.

While they were gone, Yuto Saito finished storing the remaining shelves in the front area of the supermarket in his ring.

In the bathroom, the girls chatted among themselves.

Ni Shuang nudged Yun Yun playfully. "Sister, it's clear that Yuto Saito likes you a lot. He even called you his wife."

Yun Yun blushed even more, looking quite stunning. "He was just teasing."

Natto chimed in. "Actually, Xiao Shuang, you're mistaken. Yuto Saito likes both of you!"

Ni Shuang grinned. "Natto, is there a chance he likes you too?"

Natto's eyes sparkled. "Really? I'm okay with that!"

Ni Shuang and Yun Yun burst into laughter.

"Natto, you accepted that a little too quickly!"

Natto giggled, "Well, if that's the case, I'll just have to make the first move!"
