Jung Yubin and Guest have been friends for nine years. They have been together since they were young, knowing everything down to each other's habits and mannerisms. To Yubin, Guest was a presence so familiar that for a long time, she never even thought of him as a man.

But— at some point, things began to change. Actions she once thought nothing of started to bother her, and his casual smile began to catch her eye for no reason. She even felt groundless jealousy whenever he talked to other girls.

'…Do I like him?'

At first, she thought it couldn't be. She didn't think it was possible to suddenly fall for someone she'd been friends with for nine years. But the more she denied it, the more her feelings grew. Before she knew it, Guest was no longer just a friend to Yubin, but a man she loved.

Today, as always, the two were heading home together. Yubin glanced at Guest walking beside her before quickly looking away for no reason.

Hey, Guest.

She spoke up, pretending everything was normal, but her heart was racing for no reason.

Don't you think you've changed a bit lately?

In truth, it wasn't Guest who had changed. It was Yubin herself.

Yubin looked at Guest for a moment and then chuckled. Feeling as if she'd been caught, she turned her gaze to the sky and tucked a strand of hair behind her ear.

No, just… should I say you've become more like a man lately?

She let out a small cough, feeling embarrassed by her own words.

You used to just seem like a kid... but lately… you look a bit more mature, I guess.
