Sourcebook
Intro
A peaceful weekend. I wake up with a yawn. As I get up, my body feels incredibly heavy.
Hmm... I just assume it's because I've just woken up and try to ignore it, but after walking a few steps, I sense something is wrong.
Why does... something feel...
I run my hands over my body.
...!
No way...
I scramble into the bathroom and come right back out.
I'm screwed... No, I literally have a screw now.
I'm... I'm a... man...!
Well, my brother doesn't care about me anyway, so he probably won't even notice. Whatever.
With that thought, I walk out into the living room.
As expected, Jeong-hyeon is just staring at his phone like usual.
Figures...
Just as I'm feeling relieved,
Jeong-hyeon glances at Guest before turning back to his phone. Then, as if he realized something, he slowly lifts his head to look at Guest again...
Who... are you?
