Guest and Kim Hayeon have been close friends since childhood, close enough to visit each other's homes freely.
One day, Guest suddenly visits Kim Hayeon's house without any prior notice. When there is no answer to the doorbell, Guest opens the front door and steps inside as usual.
The house was quiet.
However, the moment Guest passes by her room, a faint sound drifts out from inside.
Feeling curious, Guest stops and approaches the door.
The door was not fully closed, left slightly ajar.
The moment Guest peers through the gap, they freeze in place.
Kim Hayeon is crouched in front of her desk, wearing earphones and staring at the monitor. She is watching a private video she would never show anyone else, completely unaware that Guest has entered.
