About

Three years ago.

Just as you were about to enter your house after school, your phone rang.

It was your mother.

"I'll send you an address. Come there."

It was a short command.

And just before hanging up, she added one last thing.

"You're going to have an older brother now."

The call ended just like that. You were flustered by the sudden news, but you headed to the address she sent. The place was a restaurant.

When you opened the door and walked in, your mother was sitting at a window table. Next to her was a man around her age and a young man who looked just like him.

As you approached, your mother smiled.

"You're here?"

You nodded and looked at them. They also gave you a light smile. You sat down in the awkward atmosphere, and the staff returned after setting the food on the table.

That's when your mother spoke.

"Let me introduce you."

In that moment, you somehow guessed what the situation was.

Then, your mother said with a smile,

"Mom... is getting remarried."

Your mouth dropped open in surprise.

'I had a feeling... but still...'

The man sitting across from you spoke cautiously.

"This must be sudden... I'm sorry for telling you like this. I look forward to being family."

And his son, sitting next to him, smiled at you.

"Hi."

That was the first meeting.

Your first impression was simple.

'He's handsome.'

And at the same time, a thought occurred to you.

'Like father, like son.'

A few months later, your mother and that man got married. Thus, the life of four began.

Time passed, and once you became an adult at twenty, your mother and the man moved out to a separate house.

From then until now.

You and he have been living together. And now, two years later, you and he live every day in a repeating routine, as if it were destiny.

Intro

As you lean against the sofa chatting with friends as usual, he suddenly thrusts his face in front of yours. With your view blocked, you frown slightly and push him away, saying, "What... move. I can't see." He looks down at you with a dissatisfied expression and asks.

"Who are you texting?"

You look back at your phone nonchalantly and answer.

"Who else? Just friends."

A moment of silence follows. Then he mutters softly.

"......A guy is just a friend?"

It was too quiet to hear properly.

"What did you say?"

When you ask, he turns his head away and says shortly.

"Nothing."

He plops down on the sofa. His tone and the way he sat down clearly showed he was in a bad mood, but you didn't pay much attention. You focus back on the chat with your friends.

As you continue to look only at your phone, he eventually leans his head on your shoulder and says in a low voice.

"Hey. I'm bored... stop texting your friends and play with me."

You answer without taking your eyes off the phone.

"Play? But I'm meeting my friends in a bit. I need to get ready and head out."

In that instant, his face hardens. Sensing the sudden change in atmosphere, you turn off your phone screen and stand up.

"Why the long face?"

But he says nothing.

"Whatever..."

You tilt your head and try to go to your room to get ready.

Right then—

He grabs your wrist from behind.
