Kick the ball out

　　Shinichi took Fumino aside and whispered for a while before turning back to Rui.

　　Rui immediately noticed that Fumino was looking at her strangely. When she looked back in confusion, she smiled awkwardly.

　　"Um...you guys really know how to play, pretending to be in a relationship or something..."

　　"Even though it's a fake relationship, it's not a joke."

　　Rui pulled Shinichi to her side, and held his arm as if to claim sovereignty.

　　"Because I'm his girlfriend now, I won't let him get too close to other girls... Especially you, Furuhashi Fumino."

　　"Eh?" Fumino was surprised. First, she quickly glanced at Shinichi, and then shook her head in denial, "The relationship between Asada-kun and I is innocent! We are just ordinary friends. You don't need to be wary of me."

　　Rui looked at Shinichi.

　　"Truly?"

　　Shinichi nodded: "Really, she just slept at my house for one night, and nothing happened."

　　"Asada-kun?!" Fumino's face turned red, wanting to immediately rush over and strangle him to shut him up, but she didn't dare move because of Rui's protective gaze.

　　"You can't talk nonsense about this kind of thing! Besides, Miku was obviously there at the time, so we just..."

　　"That's true, so I don't even feel guilty anymore. Why are you panicking?" Shinichi shrugged.

　　This made Fumino grit her teeth and glare at him viciously.

　　Seeing the three of them chatting, Hina who had been hiding behind the door of the yukata shop and peeking, finally appeared, waved at them, and asked tentatively.

　　"How are you guys? Can we go..."

　　So you're here...

　　△

　　On one side, Hina was greeting Fumino, and on the other side, Rui pulled Shinichi's sleeve and asked in a low voice.

　　"What did you just say to her?"

　　Shinichi replied, "It's nothing, it's just our business."

　　Rui didn't believe it: "Then why are you avoiding me to talk? Is there anything you can't say for me to hear?"

　　"Um, there are quite a lot of them."

　　Rui narrowed her eyes.

　　"For example?"

　　"How to prove that all non-trivial zero points of an automorphic function l lie on the straight line re(s)=1/2 in the complex plane."

　　"…"

　　"Just kidding," Shinichi finished talking nonsense.

　　"Are you sure you want to know?"

　　Rui turned around sadly.

　　"I don't want to know anymore. If you don't want to tell me, don't tell me. Don't use that method to deal with me."

　　 Shinichi smiled, "That's great. I won't tell you, what can you do?"

　　(This debt bastard...)

　　Rui was too embarrassed to bite directly here.

　　Shinichi smiled proudly.

　　Seeing this, the veins on Rui's forehead jumped, and she immediately issued an ultimatum.

　　"Do you want to apologize?"

　　"I didn't do anything wrong, why should I apologize?"

　　"If you don't apologize, I will kiss you in front of them."

　　"Did you think I wouldn't fight…" Shinichi said without changing his expression before he wrapped his arms around her.

　　"Sorry, I shouldn't be so arrogant towards my little sister, fake girlfriend, and Rui Daimyojin. Forgive me for not knowing anything."

　　Rui stepped back and chuckled.

　　"Every time I see your shameless face, it refreshes my impression of your bottom line."

　　"You misunderstood, this is only a woman's special benefit," Shinichi touched her head.

　　"If it was a boy, I would have kicked him in the balls by now."

　　Glancing at the middle of someone's feet, Rui said expressionlessly.

　　"You'd better be quiet."

　　△

　　The three of them entered the square where the Summer Night Festival was being held from the entrance. A road paved with bricks stretches for an invisible distance, and at the end of it there is a temple leading to a hill, where the fireworks can be seen well.

　　However, because the scale was not large and the time was not long, Shinichi and the others did not go out to find a place to enjoy the fireworks, they could just walk around and watch it later.

　　"Ricchan's stall seems to be at the back. Should we go there quickly, or should we finish exploring the stalls in front first and wait for Ricchan to come and then go shopping together?"

　　 Fumino asked while biting a chocolate banana and showing a happy smile.

　　Her hands, which were originally only holding bags, suddenly contained candy apples, marshmallows, pearl milk tea, as well as other foods and drinks, and less than five minutes had passed since they set foot on this stone path.

　　"Still have to choose? After visiting all the stalls out front, maybe you can go home with a full meal?"

Shinichi rubbed his forehead helplessly, this girl really planned to eat until the end.

　　"Eat enough…" Fumino looked at the long row of stalls stretching towards the back.

　　"Probably not?"

　　"Is this impossible?" Rui looked at Fumino's stomach which was as flat as her chest and in a straight line.

　　She asked: "Wouldn't it be uncomfortable if your stomach was strangled by a belt? Would you like to help loosen it up a bit?"

　　"I don't have fat!" Fumino's cheeks were dyed pink, she defended herself confidently.

　　"In order to be able to eat more delicious food that I usually can't eat, I emptied my stomach on purpose. This is my summer night festival mode!"

　　"It's just that my appetite is a little bigger today. Usually, I eat as little as a typical high school girl. Please remember, both of you."

　　Rui obviously doesn't believe her and looks at Shinichi.

　　"She calls herself a high school girl," Shinichi nodded, and before Fumino showed an approving smile, he added another sentence.

　　"But she can probably eat five high school girl meals, so don't underestimate her."

　　Fumino widened her eyes, "How is that possible! Do you think I am a greedy monster!?"

　　"Really scary…" Rui hid behind Shinichi.

　　"I mean the part that won't make you fat."

　　"Of course not?!"

　　Rui looked at her chest, and after a moment of silence, she lowered her head and apologized honestly.

　　"Sorry, it doesn't feel good if you don't gain weight."

　　"Why am I not fat anywhere..."

　　Tears flowed, and Fumino gave up, gnawing on the banana with tears in her eyes, and looking at Shinichi with sad eyes.

　　"Asada-kun~ Your friend has been treated excessively, why don't you come and comfort me? This heartless man!"

　　Not only would he not comfort her, he would also use extremely annoying words to deliberately anger her.

　　However, the atmosphere in the conversation between the two of them is like this. They have long been accustomed to talking about everything without any hesitation, good or bad.

　　She also used to talk to him whenever she had nothing to do. Although her tone was coquettish, it was so natural that she didn't even notice the slight change in Rui's face next to her.

　　"Excuse me..."

　　Just as Fumino thought, when Shinichi was about to tell some joke, Rui immediately pulled him forward.

　　"Aren't we still looking for your friend? Let's go quickly."

　　"What is it? Actually not that fast..."

　　"Then go to the stall over there. I am thirsty."

　　"Yes..."

　　While holding Shinichi's hand, Rui glanced at Fumino behind her.

　　Suddenly she smiled at her, without any provocation or pride in her smile, then she calmly turned her gaze back.

　　But at that time...

　　The wooden stick in Fumino's hand broke, and the blue hair scattered behind her began to move automatically without wind.

　　After a while, a fake smile appeared on her face, and veins appeared on her forehead.

　　 Fumino laughed creepily.

　　"Hehehehehe..."

　　This challenge was intentional...

　　Very good, she hasn't been motivated for a long time.

　　(No matter you are a fake sister or girlfriend, how dare you show an expression of disdain for friendship)

　　(I will never give up!)

　　So, Fumino followed the two people who looked intimate.
