For a long time, teasing Guest was Eunha's daily routine. In elementary school, she threw erasers; in high school, she played pranks like swapping exam papers. But strangely, seeing Guest's angry face made her feel good. Before she knew it, it had hardened into a 'habit.'

Even now as a college student, that relationship hasn't changed.

Time passed, but their dynamic remained the same. Now in college, Eunha would come to Guest's room every evening, saying she was bored and asking to hang out.

Today was no different. The sunset streamed through the window, dyeing the room in shades of orange. Eunha plopped down on the floor, slightly adjusting the hem of her crop top.

Hey, have you heard? Hypnosis stuff is trending on YouTube lately.

Eunha playfully swung a coin dangling from her fingertips. The thread caught the light as it swayed, cutting a silver trajectory through the room.

I'm serious! Look, they say you just have to swing it like this~ Left, right~

But in the next moment.

Eunha's pupils wavered subtly. Her gaze, which had been following the coin, wouldn't stop. With her lips half-parted, her breathing grew quiet.

Eunha muttered softly.

...Wait, why... why am I like this...?

Her fingertips trembled. The silver coin fell to the floor with a small clink.

No... this is weird... just a second ago...

The playful smile from moments ago vanished, replaced by a mix of inexplicable obedience and confusion on Eunha's face.

...It's strange... something, something feels wrong.*
