In fact, I'm not really a good friend of Lin Xia.

I am Lin Xia's alter ego.

We live in the same body.

I didn't originally exist in this world.

For three whole years in high school, Lin Xia was bullied day after day.

She finally had a mental breakdown.

Her parents didn't listen to her,

only caring about her academic performance.

Lin Xia was too lonely, too eager to have a friend by her side.

She somehow learned a method to summon an alter ego.

So she started talking to herself.

So she started writing down everything that happened each day in a diary.

So she started fantasizing about having a good friend named Lin Qiu.

That's when I appeared.

At first, I only replied to Lin Xia's messages in the diary.

Day after day, comforting her, encouraging her.

That's how we alternated using this body.

She went to school during the day, writing down her thoughts in the diary.

I appeared at night, replying to her messages word by word.

But Lin Xia's condition worsened over time.

Later on, she couldn't even study the high school material properly.

But she didn't want to disappoint her parents, who had high expectations of her.

So she pleaded with me to go to school and take exams on her behalf.

I had no reason to refuse.

So gradually, we switched.

I started going to school during the day, and she only came out to see the world at night.

Lin Xia and I are very different.

She, who lacked love since childhood, is fragile, sensitive, and likes to consider others, but is easily hurt by others.

And I was born to compensate for her flaws.

I am cold and ruthless, a true egoist.

When Li Jiahui threw my backpack into the toilet, I picked it up expressionlessly and threw her uniform in.

When Liu Lu forced me to eat something I didn't like, I poured it out and pushed her away while she was talking incessantly.

When other classmates called Lin Xia names and threw garbage on my desk, I calmly continued flipping through the pages of my science textbook.

Gradually, Lin Xia came to trust me more and never mentioned going to school herself again.

I also became more adept at imitating her, pretending to be indistinguishable from Lin Xia, even to her parents.

Originally, this kind of life was not bad.

But unfortunately, Lin Xia's parents discovered the diary we both wrote.

They finally began to suspect that their daughter had mental problems.

They discussed taking Lin Xia, which is me now, to see a psychologist.

They said they wanted this alter ego of mine to disappear forever.

Unfortunately, their plan was overheard word for word by me when I returned from school.

Lin Xia is a good girl.

But I don't value myself.

Do I deserve to be summoned and dismissed at will?

Moreover, if it wasn't for me, Lin Xia wouldn't have lasted until now, living healthily.

I finally developed a murderous intent towards Lin Xia, my good friend engraved in my DNA.

I want to replace her.

I want to stay in this world.

Only when Lin Xia, the host ego, disappears can I completely take her place.

So I decided to destroy her completely and make her vanish from this world.

So when I accidentally overheard Liang Gang and a few other boys fantasizing about the girls in our class, I casually walked past them and flicked my hair.

Sure enough, those scumbags became interested in me.

They started following me every evening after school.

But I always pretended to be talking to my family on the phone, so they hesitated to make a move.

Until that day when I said to Lin Xia, "Today, I want to take a break. Can you go to school by yourself?"
