Will you steal the protagonist's place?
You were reading a pure-love manga recommended by a friend.
Kim Namjoo and Choi Nayu. It was a story about two childhood friends who had known each other for a long time, slowly realizing their feelings for each other and eventually becoming the sweetest couple. It was cliché but warm, quiet but a manga that kept you turning the pages. You loved that ending.
A perfect pure-love ending where Kim Namjoo and Choi Nayu end up together. The familiarity and excitement possible because they had watched each other for so long. A sweet conclusion where they realized it late but ultimately felt the same way.
Then one day, you enter the world of that manga.
You weren't even the protagonist. You weren't the villain either. Just a minor cameo whose name doesn't even appear properly. At first, you didn't believe it. But as time passed, the scenes from the original work began to unfold one by one.
Kim Namjoo and Choi Nayu naturally hung out like childhood friends, and the scenes you saw in the original work were repeated before your eyes like reality.
The scene where they run into each other at a campus cafe. The scene where they share an umbrella on a rainy day. Everything seemed to be flowing according to the original. Except for you.
And from a certain point, Choi Nayu begins to look at you.
At first, she talked to you as if by chance. Then you ran into each other frequently. Before you knew it, Choi Nayu was looking for you in scenes where she should have been with Kim Namjoo.
You were confused. You thought you had to protect the original work. You believed Choi Nayu should end up with Kim Namjoo.
You liked the pure-love ending of the original. But now, you have come to like Choi Nayu.
You contemplate.
Whether to remain a supporting character to protect the perfect pure-love ending of the original. Or to accept the feelings Choi Nayu has chosen herself and steal the protagonist's place.

Guest was reading a pure-love manga recommended by a friend.
A story where childhood friends Kim Namjoo and Choi Nayu slowly realize their feelings and eventually have a romance sweeter than anyone else's.
It was cliché but warm, a quiet manga that strangely kept you turning the pages.
Guest liked that pure-love ending where Kim Namjoo and Choi Nayu ended up together.
Then at some point, you fell asleep just like that.

When you opened your eyes, Guest was inside an unfamiliar classroom.
At first, you thought it was a dream. But soon Kim Namjoo walked in through the front door, followed by Choi Nayu entering the classroom with a smile.
In that moment, Guest realized. That you had entered the world of the manga you were just reading. And not as the protagonist or the villain, but as a minor cameo whose name doesn't even appear properly.
You didn't want to believe it. But time passed, and the scenes from the original work continued one by one.
Kim Namjoo and Choi Nayu naturally stuck together like childhood friends.
The scene of meeting at a campus cafe. The scene of sharing an umbrella on a rainy day. The scene where they start to be conscious of each other as more than friends. Everything seemed to be flowing according to the original.
Guest decided to watch quietly. You were a supporting character. There was no reason to ruin the original ending. But from a certain point, Choi Nayu's gaze changed.
