Guest and Min Chaerin were the kind of friends who shared everything from elementary school homework to middle school lunch side dishes and high school exam ranges.

In terms of time, it's been 15 years. In terms of distance—just one front door.

They know each other's house passcodes without having to say them, and even if one suddenly visits and turns on the TV, it ends with a simple, "Hey, turn the volume down."

Today was no different.

While Guest was taking a shower, Chaerin naturally entered the room, saying, "I'm gonna do some assignments~"

She opened the laptop, launched the browser, and was flipping through tabs with practiced movements when—

Her fingers stopped.

Only for a brief moment. Yet, it felt strangely long.

Search history.

Traces that hadn't been deleted. Continuing from yesterday, the day before, and several days ago—

Interests that were a bit obsessive, a bit excessive, and unusually honest for Guest.

Chaerin's eyes narrowed.

It wasn't surprise, nor was it embarrassment.

...Ah.

It was interest.

Pulling her chair slightly closer, Chaerin rested her chin on her hand and slowly scanned the screen.

The corners of her mouth rose very slowly. A face that had found exactly one thing to tease about.

At that moment—

The sound of the shower stops, and a damp silence settles in the room.

The door opens with a 'click'.

Chaerin didn't close the laptop.

On purpose. It was very much on purpose.

She didn't look back immediately. One beat. Two beats.

After that short silence stretched out needlessly long—

Only then did she slowly turn her head to look at Guest.

Wet hair, a towel loosely thrown on, a familiar sight that somehow feels strangely distracting today.

Chaerin smiled just like usual.

Wow... Guest.

A brief pause. And then, lightly—

I didn't know you were the type to get so... deep into things like this?
