This is not the date I wanted.

"Hmm... I haven't received any calls. Origami usually makes her own breakfast, and Niya wouldn't specially run over from her apartment just to have breakfast. Miku also has work today."

Although she didn't understand why Mengyue asked this question, Qinli still answered it seriously.

"I don't care about others, but if I knew Miku was coming, I would definitely hide in my room and skip breakfast."

Nanashi added with a blushing look on his face.

"What's wrong, Sister Mengyue? Why are you asking this question suddenly?"

"…Nothing, just asking casually."

Shaking her head gently, Meng Yue looked at the empty chair that had inexplicably appeared in front of the dining table in front of her, with a thoughtful expression.

20 Disharmony

==============================

Come to Zen Park at 1:14 p.m., Thursday, January th.

"what……"

Shidou sat on the swing chair of the recreational facility, lowered his head and let out a low sigh.

To be honest, if Shidou changed into a suit at this moment, it wouldn't look out of place even if he was portrayed as an office worker who angered his boss and was fired.

But in reality, Gokawa Shido's current situation is much worse than this metaphor.

Everyone forgot about themselves. After escaping from home in the morning, Shidou noticed this possibility when he recalled the attitudes of Yumezuki and Kotori at that time.

Although it is possible that Mengyue and Kotori staged a play to prank him, but if you think about it carefully, no matter how angry he is with himself, according to Mengyue's personality, it is impossible for her to do such a bad thing to deceive him. So, in order to verify his guess, Shidao came to school and went to his class to look for Tohka Origami.

But in fact, he didn't need to wait for Tohka and Origami to come to class, the confused expressions of his classmates also told him the answer to a certain extent. Whether it was his bad friend Tonomachi, or the Ai, Mai and Mii trio who had always been hostile to him, or the homeroom teacher, Ms. Kozue, they all reacted like a stranger when they saw him.

But when Tohka and the others actually arrived at the school, he was greeted by Tohka and Origami looking troubled.

"Excuse me, who are you?"

"Could it be that you are the illegal intruder that Kotori mentioned this morning?"

"—"

Shidao himself was not sure what he was feeling at that time.

His throat felt as if it was choked, the scenery in front of him lost its color, and the floor under his feet seemed fake and he couldn't touch the ground.

To be honest, if Shidou hadn't been mentally prepared beforehand, he might have burst into tears.

But even so, Shidao was still unwilling to accept this reality, and ran around to other elves to confirm whether they still had his memories.

However, the reality is so cruel.

Yakuya and Yui from the next class also expressed confusion about Shidou's appearance;

Arriving at the high-rise apartment, Shidou was turned away by Niadam, who was an impolite fan;

After much difficulty, I managed to contact Miku, but due to her male phobia, her reaction was even more exaggerated than Erya's. She screamed, "It's a call from a man I don't know!!!!!" and hung up the phone. I could never get through again.

Not long ago, Shidou finally waited for Nanazato and Yoshino to come out, but before he could say a few words, Nanazato pressed the alarm without hesitation. If Shidou hadn't run quickly, he would probably be sitting in the police station eating pork chop rice.

But every time he met everyone, it was like a heavy blow to Shidao's heart, and the little hope turned into an extremely terrible fear.

However, this is not the worst case scenario.

Not only Shidao's classmates and family, but also the neighbors around Shidao's house and the shop owners in the shopping street he often visited have forgotten him. Even when he opened his phone and looked through the old photos, Shidao couldn't find himself.

It's not as simple as being forgotten by everyone. The existence of "Gokawa Shidao" has been completely erased from this world.

"Damn it...what the hell is this!"

Shidou couldn't help but grab his hair in annoyance.

The town was the same as usual, the people were the same as usual, everything seemed to be the same as yesterday. The scenery he saw was no different from the scenery in Shidao's memory.

However, Shidao now felt helpless and confused as if he had been exiled to a parallel world.

"Is there no one... no one who remembers me?"

Suddenly, a pair of sneakers appeared in Shidao's sight. Shidao looked up suddenly and saw a girl with long brown hair looking at him with interest.

"Hey - I thought you were doing something like this. You look like an abandoned puppy. It's really ugly, Gokawa boy."

"...Meng Yue?"

Shidou said involuntarily.

"…From the looks of it, you do know me."

Seeing Shidou's reaction, Mengyue seemed to confirm something. She sat on the swing next to Shidou, crossed her legs, and looked at him curiously.

"Excuse me, please tell me what you know next."

——————————I am the dividing line where time goes back——————————————

Ever since she chased away the boy who had illegally invaded, Liangyi Mengyue had been having an inexplicable sense of disharmony in her heart for some reason.

Why would Kotori's parents let Kotori, who was only fourteen years old, live alone in a spacious two-story house?

Why would schools be closed because of a meteorite impact?

Why did Tohka and the others leave an extra seat empty when arranging the chairs?

Something was wrong. The contents of the memory could not give a reasonable answer, the danger beyond common sense was taken for granted, and the remaining habits of the body made meaningless actions without authorization.

And, Liang Yi Meng Yue herself, who has turned a blind eye to these contradictions until today.

"Meng Yue? What are you going to do?"

"I forgot to take something. I'll go back and get it. You guys go to school first."

After explaining things to everyone, Mengyue returned to Wuhe's home.

"Sorry, Kotori-chan..."

Meng Yue took out the spare key from her pocket and sneaked into Qin Li's house with a guilty conscience. Qin Li had given her the spare key out of trust, but now she was doing this kind of illegal intrusion without telling him, so she couldn't help feeling a little guilty.

(But, was this spare key really given to me by Kotori-chan?)

This question suddenly arose in Mengyue's mind. She stared at the key in her hand, trying to recall the scene when she got the key. However, her memory was as vague as if covered by a layer of white mist.

"hateful……"

Mengyue couldn't help but grit her teeth in annoyance and quickened her pace to the second floor of the Gokawa family's house.

On the second floor of the Gokawa family's house, in addition to Kotori's room, there is another room. It is not a secret door or a hidden room, but just a spare guest room for receiving guests. But for some reason, Meng Yue has been to Kotori's house so many times, but she has never used this room.

"Excuse me."

Not even knowing why she asked such a greeting, Meng Yue pushed open the door in front of her.

It was not dusty as imagined. What caught Mengyue's eyes was a very simple and clean bedroom.

“It’s unexpectedly full of life.”

Meng Yue looked around the structure of the room. On the left side of the room was a single bed covered with a green quilt. There was a square alarm clock and a few dictionaries on the bedside. Next to the bed was a wooden desk and a swivel chair. On the desk was a desk lamp and a computer. On the far right side of the room was a bookshelf full of books, and next to the door was a medium-sized wardrobe.

Walking into the room, Mengyue touched the bed sheet. There was still some residual heat in the quilt, obviously someone had been lying there not long ago.

"Did that man hide in this room before?"

Meng Yue showed a puzzled expression. This place was only separated from Kotori's room by a wall. If the other party really had ill intentions towards Kotori, Kotori would have been in trouble long ago.

"Could it be that……"

A possibility emerged in Mengyue's mind. The man in the morning did not sneak into this house when Qinli was not paying attention, but lived here from the beginning.

Thinking of this, Mengyue decided to further investigate the room to see if she could find any objects related to the man's identity.

Mengyue opened the wardrobe.

"Um, even women's clothing?"

Looking at a Laizen High School girls' uniform mixed in with a pile of men's casual clothes, and the makeup box placed under the closet, Mengyue's mouth twitched slightly when she thought of this.

"...Well, cross-dressing is quite popular nowadays. That guy's face looks quite androgynous, so maybe he is surprisingly suitable for women's clothing."

Although she was a little curious, it couldn't be considered a meaningful clue. Mengyue closed the closet and continued to investigate the bed sheets and the desk.

"Ah...I found the pornographic book."

In the innermost layer of the desk drawer and in the packaging box of an encyclopedia under the bed, Mengyue found the most common items in adolescent boys' rooms.

"In that case...then there is also..."

Mengyue turned on the computer in the room and soon found various warm-up exercise videos of young ladies in a folder called "The Road to the Philosopher".

"They didn't even add the hidden attributes, and they gave it a name that's easy to understand. Young people today have such a poor sense of vigilance."

She randomly clicked on a video and then opened a pornographic book. Looking at the content, Meng Yue couldn't help but smile with pity.

"Humph, you can tell at first glance that you're a newbie."

Ahem, I've gotten off topic. Meng Yue suddenly realized that she had forgotten her original purpose and began to search the last bookshelf.

"……No?"

Meng Yue frowned in confusion. She originally thought that if the boy lived here, there would be something in the room that could prove his identity, such as a textbook with his name on it or a photo.

However, Dang Mengyue couldn't find those things. No, to be more precise, she did find them, but there was no book with the boy's name written on it, and the photo album she found only had photos of Kotori and everyone else.

(What’s going on?)

Just when Mengyue was having a headache because of this strange situation, the cell phone in her pocket suddenly rang. Mengyue took a look and saw that it was a call from Meijiu.

"Hey, Miku, what's wrong?"

【Woohoo——Honey! 】

As soon as the phone was connected, Meijiu's panicked voice rang in Mengyue's ears.

"Calm down Miku, what's wrong?"

[Just now, a boy I don't know called me suddenly, which scared me. Then I looked at the communication interface and saw the word "Darling" on it. I had no impression of it at all. It was so scary - honey, I was so scared. ]

"Ahhh——don't worry, it's okay, don't be afraid."

After comforting Mijiu on the other end of the phone, Mengyue thought to herself that the person who contacted Mijiu might be the boy she and Kotori met in the morning.

Moreover, since Mijiu called herself "Honey" and labeled the boy as "Darling", Mengyue herself should also know the boy.

(Let’s not talk about the reason why he contacted Miku, but he actually has Miku’s contact information, which means——)

Thinking of this, Mengyue opened her phone. After unlocking it, for some reason, the screen remained on the album, which contained landscape photos without any people in them.

(When did I become interested in taking landscape photos?)

For some reason, she felt a little angry. Meng Yue took a deep breath, calmed down, and opened the address book. She found the phone number of the boy that Meijiu mentioned. As expected, she also had this number saved. However, unlike the "Darling" marked by Meijiu, her mark was a line of meaningless garbled characters.

If my judgment is correct, the line of garbled code should have been the boy's name.

——Beep! At this moment, the sound of a portable alarm suddenly came from outside the window.

Mengyue opened the window and saw that the young man was next to Yoshino and Nanashi. After Nanashi pressed the alarm, he ran away in a hurry.

"...Juna. Are you there?"

Hearing Mengyue's call, a girl with golden eyes wearing a black nun's uniform appeared on the mobile phone screen.

[Hmm? Why are you calling me all of a sudden? Aren’t you going to school today? ]

"I want to know where that boy has gone. Please use the GPS on his phone to help me locate him."

[What's wrong with that guy? I've never seen him before.] Looking at him through the camera, Junai smiled wickedly and said teasingly, [What's wrong? Is that your type?]

Meng Yue instantly looked disgusted.

"Stop being nosy. I have something to confirm. If I use my spiritual power, Kotori will notice it, so I'll leave it to you."

[Tsk~Okay.]

After ending the call, Meng Yue silently watched the boy's back as he fled.

Is there something wrong? Ever since she woke up this morning, a voice has been echoing in Mengyue's mind.

Then, after paying a little attention, Meng Yue discovered that although her daily routine seemed to be the same as usual, it was actually full of flaws that could not be ignored.

What have I overlooked? What have I forgotten? Something that seems to be very important, but I just can't remember it.
