My girlfriend is Ying Lili

"what happened?"

Kiyosuke Hashima looked down.

Ebina raised his small face and plucked up the courage to say, "Tomorrow night, shall we go to the park to practice together?"

"You should ask Xiao Qian about this matter." Kiyosuke Hashima looked at Hamster Qian and kicked the ball over. "After all, it's your game with Xiao Qian."

Xiao Mai hesitated for two seconds, and quickly made a decision. He raised his hand to hold the wind-blown hair beside his ear, with a gentle voice: "Then go together, I also want to practice more."

No way, Eilao Ming looked over with a cat's eyes begging for a small fish, no one can refuse with a hard heart, right?

Kiyosuke Hashima nodded slightly: "Then go together."

Ebina breathed a sigh of relief immediately, "Senior, Xiao buried, see you tomorrow!"

...

The campus life on the second day was calm and plain.

It was school time again in a blink of an eye.

Kiyosuke Hashima failed to leave today, but the teacher arrested the young man, who was taken to help move things.

After all the trivial matters were dealt with, the sun had already begun to set. Kiyosuke Hashima returned from washing his hands from the bathroom, picked up his schoolbag, and was about to go back to the apartment. The mobile phone in his pocket suddenly vibrated.

Kiyosuke Hashima took out his cell phone and found that it was a message from Kato.

Chapter 899

"Hashima-kun, have you returned to the apartment?"

After receiving news from Kato, Kiyosuke Hashima, who had just walked to the school gate, stopped immediately.

"No, still at school."

Kiyosuke Hashima sent another message: "Is not feeling well?"

Wait a few seconds, and soon a new message appears on the screen.

"No discomfort."

The sage classmate quickly said:

"Um... I want to ask Hashima-kun for a little something."

"The cheerleading training has ended, and when I changed clothes, it seemed to be ignored by everyone."

Kiyosuke Hashima didn't react for a while: "What's the matter?"

It took a few seconds for Megumi Kato to send a message.

"The locker room door can't be opened, it seems to be locked."

"..."

This kind of thing can be encountered by you, and the sense of existence is still too low!

"Don't laugh."

The sage classmate sent an emoticon pack with a bandage to seal his mouth.

"Can't help but what to do?"

Kiyosuke Hashima couldn't help but smile, and Zhizhu was holding it all the time. He didn't expect that there would be a pitiful day when he was begging for help. He couldn't help but smile.

"You can only laugh for one minute at most."

"Thank you Kato-sama for his generosity."

"..."

"I understand the situation." Kiyosuke Hashima took a light breath and turned and walked towards the school. "Where is the dressing room, I will pass."

The sun is setting.

The sky is full of sunset clouds.

The huge campus has quieted down, and most people have left, but there are always teachers who stay in the school to patrol and inspect.

Kiyosuke Hashima found his teacher Suzuki Kiko, took the key from the opponent, and quickly walked to the door of the women's dressing room where Kato was.

"Boom."

Raising his hand and knocking on the door lightly, Hashima Kiyosuke whispered, "Kato?"

"Hashima-kun, I am here."

Kato Megumi's voice came from the door.

"I got the key, and I will open the door."

Kiyosuke Hashima opened the door with the key and pushed the door into it. The pattern of the men's locker room and the women's locker room were almost the same. For Kiyosuke Hashima, who had been to the women's bathroom, there was no psychological pressure at all.

"reading a book?"

Kiyosuke Hashima was surprised.

I thought I would see Kato Yun playing with his cell phone lightly when I walked in, but I didn't expect Kato to read a book.

"It's the homework left by the teacher today." Kato said with a pencil in his hand and pursed his pink lips. "It just happens to be free now. I finish writing in advance and I can watch TV at night."

Kiyosuke Hashima walked to Megumi Kato and found that Kato was doing his math homework, and then... he saw two mistakes at a glance.

"This question is wrong."

"Well?"

"Permutations should be used here, not combinations."

"I don't understand." Kato looked up, with a little distressed expression on his face, "The teacher sounded very simple in class, and the sample questions in the textbook looked very simple. When I was writing the homework, I realized that the questions were super difficult. I don’t even know if I read it or not."

It is the truth of the universe, the cornerstone of all things, and all beings are equal before mathematics.

Even the sage classmate sitting on the frosty sky would be helpless and troubled in the face of mathematics.

"The reason why permutation and combination appear in the compulsory high school mathematics is because it is the basis of probability. In fact, it is not difficult..."

Kiyosuke Hashima decided to make up for Kato. Trigonometric functions, conic sections, and limit inequalities are not clear for a while, but the permutations and combinations are really simple-the number given in the question is only a few dozen, sometimes You can even use exhaustive methods to list all the answers. Unlike climbing a technological tree, you need to unlock the pre-knowledge points to learn. The only operations that appear are elementary school multiplication.

Just like swimming and cycling, once you master it, you can basically go smoothly without any problems.

As for people who can't learn permutations and combinations...obviously, logical thinking is not strong enough.

Kiyosuke Hashima talked about the logic rules for a while, and suddenly heard the sound of footsteps approaching outside the door, and closed his mouth subconsciously.

When a boy appeared in the women's locker room, it was unavoidable to be found in trouble.

A faint voice of dialogue came in from outside the door, it should be the teacher in charge of patrolling the school.

Hashima Kiyosuke and Kato sat together and kept quiet. After a while, the footsteps of the teacher patrolling outside the door quietly disappeared.

"Hashima-kun, it's late, let's go back first."

Kato Megumi said softly.

Kiyosuke Hashima glanced at the phone time. It was already 6:30 in the afternoon, the sky had dimmed outside, and the dusk had begun to fall quietly.

"Let's go."

Kiyosuke Hashima got up and walked to the door, reaching out to hold the doorknob, the expression on his face suddenly solidified.

Ke Kato, who followed him, tilted her head slightly, "Hashima-kun?"

"call……"

Kiyosuke Hashima closed his eyes and took a light breath, his expression serious: "I'll study in the classroom next time."

"Eh?"

"The door won't open."

Kato Megumi: "..."

"It should be the patrol teacher who passed by the door just now, and he locked the door easily."

Kiyosuke Hashima was a little bit annoyed. He knew this would happen, and he left just now. As expected, he shouldn't stay for a long time. The ancients did not deceive me.

"It feels a little bit troublesome." Kato Kee pursed her pink lips. "Even Shiba-senpai or Yinglili should have gone back at this point?"

Needless to say, Senior Sister, members of the Homecoming Department must have left school long ago.

Zhaili is still possible.

"excuse me, may I ask."

Kiyosuke Hashima took out his cell phone and sent a message to Eiri.

"where is it?"

Ying Lili came back soon and said, "I just got home, you asked me where I am doing?"

Everyone had already gone home, and it would be very troublesome to call Zakuli to come and open the door. Kiyosuke Hashima silently crossed out the option of'Summon Zakuli'.

"Come to the park to run together at night?"

"Give up, impossible, goodbye."

"..."

Kiyosuke Hashima immediately sent another message to Suzuki Nozomi, but unfortunately the teacher didn't know what he was up to, so he never responded.

"Hashima-kun, don't worry."

Kato is as calm and calm as ever, as if he doesn't care about the current predicament at all.

Kiyosuke Hashima walked around the locker room and walked to the window, his eyes condensed suddenly.

"This is the second floor, right?"

"It's too dangerous." Kato Megumi instantly understood Hashima Kiyosuke's thoughts, and Liu frowned slightly. "It will be hurt."

"I will definitely not jump on the third floor, and there will be no problem with the second floor."

The locker room is located on the second floor, and the windows can be opened directly. Kiyosuke Hashima pondered for a moment, and with his current physical fitness, it would be no problem to jump down.

"No."

Kato reached out and held the corner of Hashima Kiyosuke's clothes, and shook his head slightly, "There must be someone in the school who hasn't left. Maybe someone will pass by the window later."

Kiyosuke Hashima did not insist, "Then let's wait a few minutes."

The two stood by the window, silently looking out.

The sun has set, and the clouds on the horizon have been soaked in the afterglow of the setting sun, making them extraordinarily magnificent.

"The clouds are so beautiful~" Kato raised his eyes to look at the sky, and said softly, "It feels like I haven't looked at the sky for a long time."

Of course it's been a long time, because you spend most of the day looking at your phone!

Kato is undoubtedly a mobile phone control, don't look at it now is super calm, but if the mobile phone is out of power, it will definitely not be as indifferent as it is now.

There is wind blowing.

The evening breeze in autumn is quite cool.

Kato raised his right hand and gently held the hair tossed by the wind. The former girl with a bob head had a ponytail unknowingly.

Seeing the girl's delicate profile in the afterglow of the setting sun, Kiyosuke Hashima suddenly remembered a poem.

You stand on the bridge and watch the scenery,

The people watching the scenery are looking at you upstairs.

Fortunately, I am not upstairs, but by my side.

After waiting for a while, no pedestrians passed downstairs at all.

"It's dark soon, I jumped down."

Kiyosuke Hashima has made a decision.

Kei Kato pressed her pink lips: "Hashima-kun, be careful."

"Do not worry."
