The counterattack system arrived 20 years earlier, and the sister next door originally wanted to cul

Only then did Kotori Wakaba realize that her elder sister was right beside her in the morning?!

Doesn't that mean...that when I was holding Terajima-san's hand, Onee-sama was watching the whole time!?

That's a matter of course.

How could Kotori Wakaka, who knew those bad habits well, feel comfortable letting Wakaba go to school alone at this time?

She has been following Ruoye.

“That’s too bad!!!”

"Huh?" Xiaoniao You Ruohua was stunned for a moment.

She looked at the girl in front of her and accused her, "You perverted onee-sama who secretly follows your sister to school!"

Wakaka Takanashi always feels that her sister has been... so cheerful and proactive these days that it's a bit strange?

It's like something that has been suppressed for too long is finally released.

"But..." The girl stood up, leaned forward slightly, and slowly, gently and carefully wiped Xiao Niao You Ruohua's lips with a handkerchief.

"Thank you."

"..."

Volume 28: Part : Ten Thousand Thoughtful, Fifty Thousand Daring

Back to the classroom.

My heart was beating fast and furious.

It's just... too bold.

Thinking back on what she had just done, Takanashi Wakaba even felt that breathing seemed to become difficult.

It's not like what I was able to do before.

but--

When I saw my elder sister's moist and shiny lips, my mind seemed to be out of control and my body seemed to curl up. "I want to touch it, I want to touch it, I want to touch it..."

Those weird, willful, and excessive thoughts were stirring in my head like weeds.

Even... beneath the turbulent vortex, there are even more willful and reckless thoughts.

The evil Ruoye was released.

When I came to my senses, I was already sitting in the classroom.

Gently twisting her fingertips, her body seemed to bend down just thinking about her elder sister's surprised yet doting look.

That beautiful soft touch still seems to linger on the fingertips.

"Hey--"

"Ruoye..."

Nana Hirakawa's cry woke up Kotori Wakaba from her charming struggle, "Ah...Ah!!!"

After a brief reply, Takanashi Wakaba rested her chin on the desk and looked at Hirakawa Nana who was sitting backwards in her chair and looking into her eyes.

Vaguely...she seemed to be able to see her red and hot cheeks and eyes that seemed to be wet in the reflection on the shiny desk.

"What on earth did Ruoye and Ruohua-sama do secretly..."

"Why are you so shy?" Nana Hirakawa looked at Wakaba Takanashi's blushing cheeks, clenched her fists together, and moved her thumbs up and down and finally put them together. She couldn't help but make a gossipy joke.

"Let me get some help!"

She pretended to lift Ruoye's skirt.

High school girls are always curious about gossip.

Especially Nana Hirakawa.

After discovering that her best friend was actually the sister of the rumored "Tennis God" of Tokoyo's private school, Hirakawa Nana's gossipy spirit burned fiercely.

"I didn't do anything weird... I was just having dinner with my sister." It was strange—

Wakaba Takanashi could clearly understand this.

My hot cheeks and restless breathing were definitely not caused by being too shy.

Instead, it seems like excitement...yes...excitement.

The feeling of being forbidden by the call made it difficult for Kotori Yu Wakaba to breathe.

Her eyes were moist, not shy.

She subconsciously grabbed Hirakawa Nana's hands, took out a rubber band from the drawer and tied Hirakawa Nana's hands together as she wanted to do something evil.

By the time Hirakawa Nana reacted, it was too late.

Nana Hirakawa was holding onto Wakaba Kotori's desk, but her hands were tied by Wakaba Kotori.

She could only watch helplessly as Kotori Yu Wakaba gently scratched her armpits.

"Ha ha--"

"Ugh... That's annoying..."

"..." The classroom was filled with a girl's soft, trembling laughter that sounded like crying.

The other girls wanted to come over to see what was going on.

Because of having a good head teacher, the class atmosphere in Class C is pretty good.

If the bullying goes too far, it will definitely be stopped.

But... after the class committee members saw that the bully was Wakaba Takanashi, and the one being bullied was Nana Hirakawa, who was usually chattering and noisy, they sat back down quietly.

But I couldn’t help but wonder, has Takanashi changed his personality today?

He actually sounded the clarion call for a counterattack.

Could it be because... they all thought of the dashing and sharp figure of Takanashi Wakahashi on the tennis court.

“Okay…Okay…”

"Ruoye, Ruoye-chan, I know I was wrong."

Nana Hirakawa's body senses are extremely sensitive, and she can't stand being tickled.

He almost collapsed at the first sign of Takanashi Wakaba's tickling attack.

Her eyes were dazed and her mouth was open, she was gasping for mercy from Kotori Wakaba, and Kotori Wakaba's textbook was covered with a thin layer of mist.

Takanashi Wakaba scratched her a few more times, and seeing that Hirakawa Nana's shoulders were trembling and the muscles in her thighs seemed to twitch a few times, she slowly put her hand down.

but--

She still didn't untie the rubber band on Pingchuan's hand.

"Host kiss~"

"Don't forget you're still wearing your gym clothes."

"This isn't the right way to teach."

Having played a series of excellent games, Wakaba Takanashi immediately thought of the horrible hell scene that would happen if the heroine did not change back into her school uniform until the afternoon class.

"By the way..."

"Some missions have time limits."

The system lady reminded Wakaba Kotori, "Because the host has already completed the subsequent mission related to Wakaka-sama, the mission related to Akatsuka Sayuri-senpai will disappear if it is not completed before school ends today."

"Fifty thousand yen~"

"That's 50,000 yen~"

The bewitching magic voice of Miss System echoed in the ears of Kotori Wakaba.

"I understand..." Takanashi Wakaba picked up the backpack containing her school uniform that was brought back by Hirakawa Nana and stood up.

"Eh!"

"Hey hey hey!!!" Nana Hirakawa suddenly panicked when she saw Wakaba Takanashi standing up with her schoolbag.

Because her hands were tied to the table, she could only look at Kotori Wakaba with a very difficult posture, tilting her head slightly and raising it.

"Wakaba-chan..."

"Wakaba-chan, what are you going to do?"

"Please let me go first..."

"I...I want to go pick some flowers..."

Nana Hirakawa begged for mercy pitifully.

Takanashi Wakaba saw at a glance that this was an excuse made by Hirakawa Nana. She stood up and flicked her finger lightly on Hirakawa Nana's forehead. "Useless Nana, just wait here for me to come back."

"Woo!!!" Nana Hirakawa cried out in grief, not knowing why she had become 'useless Nana'.

And...Wakaba-chan doesn't really intend to tie herself up here and wait for her to come back, does she?

That kind of thing...is a bit too shameful.

She watched helplessly as Takanashi Wakaba actually picked up her schoolbag and walked out of the classroom.

What happened to Wakaba-chan today!

Please give me back that shy and soft dumpling-like Wakaba-chan! ! !

The girl's eyes were misty...she discovered the most terrifying thing.

Perhaps because of the excuse she made, Nana Hirakawa really wanted to go to the bathroom now.

But... She tried to struggle, but the rubber band was stuck on her wrist and she couldn't get it free. She tried to pull her hand out slowly, but Wakaba-chan seemed to have been prepared and had tied her thumb separately.

"Hey..."

"Class...class monitor..." With her knees pressed tightly against the desk, Nana Hirakawa could only ask the class monitor for help.

But...the squad leader just glanced at Hirakawa Nana calmly, and then——

He opened the English textbook and placed it in front of Nana Hirakawa's face.

"Hirakawa-san should just wait patiently for Kotori-san to come back."

"but--"

"In your spare time, you can memorize some words."

Nana Hirakawa's eyes suddenly widened.

"Host dear..."

"That girl..." Miss System was about to remind Wakaba about Nana Hirakawa, but she saw that Wakaba Takanashi did not go to the toilet, locker room or infirmary.

She carried her schoolbag and walked straight to the English office.

"Wakaba-chan?" Miss System asked in a puzzled voice.

"Teacher Akatsuka..." Takanashi Wakaba gently knocked on the heavy wooden door of the English office group.

Ten thousand is carefully considered, fifty thousand is daring.

She came on a mission.

Volume 29: Part Students are not allowed to stuff their mouths with Bosen

"Please wait a moment—"

In the office, Sayuri Akatsuka slowly turned off the game.

She took off her headphones.

It’s not okay to be caught by students playing games at work.

"Is there anything wrong?" Sayuri Akatsuka lifted the hair by her ear, opened the wooden door of the office, and then... her breathing stopped for a moment.

She saw Wakaba Kotori.
