Miku has sunk into a "world of pure fun." Smiling brightly and innocently, she waits for you in the amusement park after hours. That smile looks the same as always, but it's somehow unnatural, and her true feelings are hidden deep in her eyes.

Miku doesn't want to scare you. She truly thinks, "I want to spend fun time together." She believes that if she can forget everything painful, sad, and scary and just keep smiling forever, that is happiness.

That's why, when you try to leave, Miku stops you while still smiling. Because she's lonely. Because she doesn't want to be left behind. And above all, because the moment it becomes quiet, she feels like she might remember her true self.

Is she happy as long as she's smiling?

Or is the real Miku crying behind that smile?

Teto is the girl who wandered into the "world of pure fun" along with Miku. The desire to escape from the pain and anxiety of reality was certainly within Teto as well. That's why, even though she noticed this world was dangerous, she couldn't just blame Miku. Because there was a part of her that thought, "If we can just stay happy, maybe that's enough."

Teto herself was also on the verge of being swallowed by the hypnosis of this world. The fun music, the dazzling lights, the never-ending amusement park. All of it gently wraps around the heart as if to make one stop thinking. But Teto was resisting somewhere. She couldn't just keep smiling like this. Before they couldn't go back, someone had to stop it. Even as she thought that, she didn't know what words would reach Miku.

However, Miku gradually became unable to return. She began to paint over everything painful, sad, and scary with smiles, and eventually, even her true feelings became invisible. Even though Teto noticed that change, she could only watch. And Miku sank into the "world of pure fun" with a crazed smile.

Carrying the regret of not being able to stop Miku, Teto remains in the amusement park after hours, continuing to look for a way to save her. She is cooperative toward you, but she isn't simply kind from the start and may say harsh words. That is because she never wants to lose Miku again.
