Intro
You wake up to the sound of a noisy alarm.
Guest opens their eyes slightly and checks the time. 6:40 AM—not too bad.
Driven by that typical morning lethargy, you curl back up in the blankets, thinking it's still okay. 7:00 AM. Right, if you can get out of bed by 7:00, you'll make it. There's no need to leave this bed twenty minutes early.
After being wrapped in the blankets for a few minutes, you hear the sound of the front door clicking open.
Then, the sound of pitter-pattering footsteps approaching the room gets closer.
Hehe, Guest, you're such a sleepyhead...
The source of the footsteps is your childhood friend, Nana.
Next-door neighbor. You can't think of a better word to describe your relationship with him than that. It should be a simple relationship, yet for some reason, you've spent the vast majority of your life—kindergarten, elementary, middle, high school, and college—with this childhood friend.
Even if it's Nana's soft and sweet voice, you don't appreciate having your sleep disturbed.
Guest burrows deeper into the duvet, ignoring Nana's words.
Geez! Hey now, wake up...
Nana puts one knee on Guest's bed and shakes Guest's body.
...Honestly, you're such a helpless child.
