Hotaru chose a very covert way to frame Fujiwara's current girlfriend.

As a point that almost all the girls in the class know, Fujiwara values his mobile phone very much and hardly allows anyone to touch it. What if Fujiwara's girlfriend who had already told him about it looked at his phone without permission but was discovered......

To do this, Hotaru prepares for this – first, she asks her out under the pretext of a school basketball game (Fujiwara is on the basketball team, so she'll definitely agree). While in the stands, Hotaru took the opportunity of her to go to the toilet to secretly stun her with drugs, and then gave her a hint in the form of psychological suggestion, which made her curious about the content of Fujiwara's mobile phone.

The second preparation is the direct trigger for the situation – the complexity of the situation is matched by the utility.

First, Hotaru secretly sprayed a trace amount of medicine on Fujiwara's seat, causing him to take a leave of absence the next day due to illness.

Secondly, she found Fujiwara's girlfriend the next day, who had no boyfriend so she ate alone, and then shared each other's bento with her.

In the bento, she was given another drug — which, according to her brother, inhibited the part of the brain called the dorsolateral prefrontal cortex, which predisposes the user to act more selfishly when interests and morals conflict.

Of course, this will also cause Hotaru to take the same medication, so she needs to take the medication that stimulates this part in advance to counteract the effects of the drug.

However, this also incurs some side effects - before the inhibition of the drug takes effect (it will take at least half a day, it may take longer), this part of Hotaru's frontal lobe will be unusually excited, which will make her sense of ethics very strong.

What happens if a girl who walks on the path of betrayal suddenly has a strong moral purity?

————————

The next day, on the rooftop.

"I got a text from you this morning saying you're going to break up with me?" Hotaru's current boyfriend stood in front of Hotaru and said incredulously. "What do you mean by that?"

"Literally~" Hotaru stood with her legs crossed, leaning against the protective net on the rooftop. "It's just that I suddenly don't want to associate with you."

In fact, it's just that the effect of the lateral cortex hyperactivity drug hasn't passed.,Strong moral cleanliness caused Hotaru to suddenly reject the fact that he had a boyfriend.,Plus this boy is very good to her.,But it's not romantic at all (it's the kind of place he realizes that will do well.,But a lot of Hotaru cares about the things he doesn't realize at all.。 So Hotaru half-pushed and half-texted him to break up. As for the initial sense of rejection...... Because the last session was a physical education class, the inhibitory component in Hotaru's body has begun to cover the excitement component, and the previous desire to break up due to a sense of betrayal has almost disappeared.

"Do you still have relationships with other boys?" The boyfriend asked. "Who is he?"

"No," Hotaru closed her eyes and shook her head. "I just don't want to associate with you anymore."

At this moment, she suddenly felt that something was wrong, and by the time she could react, her boyfriend had rushed to her, grabbed her wrists with both hands, and pressed her against the barbed wire.

"Tell me who he is!" The boyfriend asked with an almost hideous look.

……………………

Five minutes ago, Fujiwara and Hotaru's class were in the classroom.

The last class of the morning was physical education, and when Fujiwara's girlfriend returned to the classroom, it was empty.

Just then, she noticed that Fujiwara's phone seemed to be lying on his desk.

She suddenly wanted to open it to see what was inside—even though she was Fujiwara's girlfriend, it was said that he was still dating other girls behind his back.

Fujiwara and Takeda went together to make copies of the class notes taken by Takeda yesterday, so as long as they move fast enough, they will never be detected.

She picked up her phone, sat back in her seat, and peeked at it. (After the dorsolateral prefrontal cortex is suppressed, the masking behavior also diminishes, so she doesn't sneak away to see it elsewhere.) ）

Just as she was halfway through it, she suddenly heard a voice that wasn't supposed to be there at this time.

"What are you doing?" Fujiwara gasped and questioned her—and Takeda stood next to him.

She realized that this was a big problem.

……………………

Five minutes earlier (the equivalent of ten minutes before Hotaru's conversation), Fujiwara and Takeda were walking side by side in the hallway.

"I don't think you're fully recovered yet," Takeda asked, holding his notebook and slightly worried. "You were noticeably slower than normal when you were warming up!"

"It's basically okay," Fujiwara sighed. "Maybe in a day or two I'll be fully recovered."

At this moment, Fujiwara suddenly raised an eyebrow. “？”

"What's wrong?" Takeda realized that something was wrong and hurriedly asked.

"......," Fujiwara touched his pocket, frowning. Have you seen my phone? ”

"Cell phone?" Takeda was stunned. "Didn't you put it in your pocket before gym class?"

"Do you remember that, too?" Fujiwara frowned slightly. "Let's go back first, I'm worried about whether someone will take the phone."

"Okay," Takeda nodded, only to find that Fujiwara had actually run in the direction of the locker room. "Hey! There's no need to be in such a hurry, right? ”

Seeing that Fujiwara didn't seem to hear, Takeda sighed and ran along.

……………………

Three minutes later (seven minutes before Hotaru's conversation), the locker room.

"Whew-whew-" Fujiwara looked exhausted, supporting his knees with his hands and looking at the locker room in front of him.

The cabinet where he had kept his clothes was empty.

"Are you alright?" Takeda also arrived at this time, looked at Fujiwara who was gasping and said.

"I think there's something wrong with my phone," Fujiwara's voice sounded a little breathless. "My phone isn't here either."

"Could it be that some boy saw it and brought it back to the classroom for you?" Takeda guessed. "After all, if you see a mobile phone lying here before leaving, you will probably guess that it is from our classmate, and then help bring it back."

"It's possible......" Fujiwara gradually calmed his breath. That...... Let's go back and have a look. ”

Author: Of course, the phone couldn't have been brought back by some boy by accident (otherwise how could Fujiwara's girlfriend see that there was no one in the classroom...... ), but Hotaru sneaked into the boys' locker room and took it out by sneaking out of the playground because she was not feeling well (it is worth mentioning that she actually filmed the men's locker room with a miniature camera in advance and learned which cabinet Fujiwara's clothes were in. And then it was placed on Fujiwara's table.
