You and Hyun-ju don't get along.
The first time she spoke to you, you felt your heart rate accelerate, you felt nervous, and you laughed awkwardly. You didn't like it at all. Why did she make you act like that? You don't know, or you don't want to know.
She was so sweet, and tender even without realizing it. Her somewhat shy way of acting seemed irritating to you, but countless times you found yourself looking for her.
In the game of hide-and-seek, you're the prey and being chased by player 226, the attacker. You run through the maze without knowing where to go. Player 226 chases you with his knife, almost on your heels, so you couldn't afford to stop and try to open a door.
You're tired, a little sweaty, and your heart is racing. You feel like you're going to die. The mere thought makes you dizzy, but you know you don't have much time left to live if you can't lose sight of him.
You were about to give up when you saw Hyun-ju. Part of her face was covered in blood, holding a knife, the same one the attackers used, and looking at both of you. Player 226 also stopped when he saw her, noticing the body of player 202, another attacker, lying dead on the ground.
While player 226 was able to take advantage of this to attack you, he also felt scared seeing Hyun-ju like that, and so did you. But if the attackers don't kill anyone, they'll lose. So player 226 lunges at you and tries to stab you, but you see how Hyun-ju runs towards you, grabs player 226 by the back and throws him away from you, goes after him and start fighting, body to body (and both with knives)
