The following is my own understanding, everyone is welcome to add to the discussion (ˊωˋ*)

Let me tell you what I know about the plot

What I want to talk about is not the lan incident nor the multi-ship incident between W and Miss Lan, Miss Internet Celebrity and Miss Musician, etc. What I want to talk about is the incident between W and Mayonnaise.

From the plot, everyone knows that W and Mayonnaise know each other. From the photos, we can find that these two people once stayed in the "Dream Home" orphanage.

The boy and girl in the picture also appeared in the mayonnaise room. I think this is the past of the two of them (I put it in the order of the pictures. Please correct me if I put it wrong. I think this should be in chronological order)

When W was a child, there was only one person

One day I met mayonnaise and became good friends with mayonnaise

Mayonnaise's hair accessory only has a green bow. She dreams of having bows of many colors.

From this picture, you can see that Mayonnaise's hair accessories have changed. She is standing under the sunflowers, which means that she has left the orphanage and lived her own life, and the future is full of sunshine.

This picture of Mayonnaise's hair ornament has changed back again. There is a snowman standing next to it, and the girl is crying next to it. I guess that W left the orphanage, leaving Mayonnaise feeling lonely alone and wanting to build a snowman. Accompany yourself, but you will still miss W

W did not live well after leaving the orphanage. It can be seen that he was bullied by other children and could only hide in the trees, so when he read the book "I Don't Want to Go to School", W resonated with it (the mayonnaise on the side also She doesn’t want to go to school, and the "Art of Communication in the Workplace" shows that although Mayonnaise likes to yearn for the second dimension, she still tries to integrate into society and work)

As we continue to decrypt, we will also discover these four books. The books talk about their present, and behind the hole-in-the-eye paper is their childhood (the content below is arranged in order of books 1-4 )

Aomame describes W Tengo and mayonnaise

When they were children, the two communicated through hole-in-the-wall paper. W asked Mayonnaise what kind of books she liked, and Mayonnaise said she liked two-dimensional books.

The timeline turns to the present, and W meets Mayonnaise again. "It seems like I have seen a similar scene before, but I can't remember it." The two met again in a similar way. Mayonnaise was wandering in the documentary literature area, and Egg Yolk Jiang recognized her childhood playmate and her favorite person - W. She knew that W liked to read documentary literature, but she didn't have the courage to speak. In desperation, W took Mayonnaise to the fictional literature area unknowingly, indicating that in the W subconsciously has an impression of mayonnaise and knows what she likes better.

In the Tengo chapter, Mayonnaise really wants to mark the day when they meet again as an anniversary. It can also be seen from the article that Mayonnaise has a very bad relationship in her current family. She yearns for the two more than the cruelty of the real world. The beauty of dimension

As for the fact that W’s profession is to record cruelty, I’m not sure. I’ll explain it to myself.

The story here is that neither of the two people lived a very happy life in their new family.

The timeline shifts to the present, and W finds in the classmate directory that Mayonnaise left a message to W, "My graduation is complete with your company." In this cold and cruel world, Mayonnaise's message is so special and full of warmth.

Mayonnaise, who was alone, had her chair occupied and was let go by W. She imagined that W was carefully preparing for the date... (Judging from the description in the book, it should be Valentine's Day)

Both of them have expressed their love for each other in the past

The timeline moves to the present (it can be seen from the article that it should be the Mid-Autumn Festival). Although W has money, power and a woman, he is still very lonely inside, and Mayonnaise also feels very lonely.

"It takes courage to face yourself, the past, the present, and the future. I hope we can all do it."

"Go fall in love with your young and promising boyfriend! Happy girl."

It shows that at this time, the two of them have already had the consciousness to face the future together.

The timeline turned back to the present, and the two of them were together again, eating in a noodle shop. He hoped that today could end slowly, which showed that W still really likes a little mayonnaise in his heart (although he hasn't thought of it yet)

When Mayonnaise was chatting with W, she knew that there were many girls who liked W, but she couldn't hold back and changed the topic. W thought that she would definitely come out next time he asked her out. Looking at Mayonnaise, she felt So happy that I forgot everything.

Mayonnaise wrote in her diary that she wanted W to see her true self, and later we also learned that the Internet celebrity revealed Mayonnaise’s true appearance. Perhaps she has experienced a lot of suffering since leaving the orphanage, and there are still scars on her face. Scars that cannot be removed (As for who told the internet celebrity what mayonnaise looks like, everyone must know it)

The book we found under the tiger rug tells us exactly where this all started.

We know that W was abused in childhood and did not feel warmth. He regarded his family as a step to climb up and stand at the top of society, so he did a lot of dirty things.

W becomes better and better, but the flaws caused by childhood begin to magnify and distort W

Even these girls are only regarded as the targets of the strategy, and the only one that does not show "already captured" is mayonnaise. From the front, it can be seen that W really likes mayonnaise more or less (although this is just my little one) Tucao, why do you want to expose the mayonnaise? You are a scumbag!!) And he can also feel that the mayonnaise is not "already conquered". W does not regard mayonnaise as his real target, but prefers the object he likes.

Although W has grown up and reached the peak of his life, mayonnaise is still unforgettable for him. There are only two things in the very important safe, one of which is mayonnaise.

But why does Mayonnaise know that W has another girl who likes W and is still together? Why does Mayonnaise still like W after knowing the harm that W has caused her?

I think this has something to do with Mayonnaise’s childhood. For Mayonnaise, she only has W. She regards W as her most important person. W is her world. She has completely relied on W. I feel that Since I started to like it, mayonnaise is more dependent on W, and I can no longer leave it. Even though I know rationally that I want to moisturize quickly, my emotions are all on W and I can't get rid of it.

This shows that in childhood, Mayonnaise was not able to establish close relationships with others, including her own family. No one could guide Mayonnaise to make new friends, and it would be difficult for her to integrate into society when she grew up. Lack of care from others, and W is the only person who gives her warmth and care, so she becomes hopelessly dependent on W

As for the end, W recognized mayonnaise

The two of them indulged in a dream together and lived a happy life

I personally think this can be regarded as two people eloping together, eloping in a dream and being together forever.

——————

As for some other details, I don’t know, but I think they are relevant, so I’ll put them here first.

The photo is the lightest object here, what does it symbolize, and what do the other objects symbolize (it’s not really just weighing it)

You have the Statue of Liberty in your home, hoping to gain freedom. You must be trying to get rid of the darkness of society, right? I feel that he has been assimilated into the dark world...

I think the books and paintings inside have certain meanings. For example, the paintings here (although I have forgotten the name, but I remember it seems to mean that Joan of Arc leads the masses to resist oppression) symbolize the struggle between the heart and reality. The struggle against society (and I mentioned earlier that it takes courage to face oneself, it should be a struggle against the past)

So I feel that the paintings here also have meanings, especially the first painting that runs through the fourth room (ok, I forgot its name, I give all the knowledge back to the teacher). I think they should have their own Meaning

The last thing I still have questions about is why I remember Beethoven's "Moonlight" so clearly, which is used throughout the game. Thanks to the Conan Moonlight murder incident, it is still fresh in my memory... So I went to Baidu to find out the meaning of "Moonlight":

The legendary story of "Moonlight" shows the great musician Beethoven's love for the poor people. At the same time, it also tells people that the production of beautiful music depends not only on rich imagination, but also on noble and sincere feelings.

The above intercepted part of the content from Baidu. I personally think the author is hinting at the meaning of some games. Don’t be swallowed up by darkness like W and turn yourself into a dark person. Be brave like mayonnaise... (I personally feel like this I understand, but it may not be comprehensive or accurate) Anyway, I just feel that Moonlight Song is hinting at some content in the game. The ice is a bit big and deep, so I can only dig up to this point. Everyone is welcome to discuss it!
