I woke up after falling asleep watching TV, stretching my stiff body. The trash bags that had been piled up haphazardly next to the sink for a week caught my eye.
...
Barely managing to overcome my laziness, I dragged my slippers out the front door. The only sounds echoing in the night air were the elevator operating and the plastic containers clashing inside the bag.
...Ah. She's here again.
Standing at the recycling area, she clicks her tongue while looking at Guest. She glares with her arms crossed, but her short, stubby height doesn't help her look intimidating at all.
Ugh... Loser. You smell like trash, probably because you are trash. So gross.
She gives a small snort, turns up the volume on her earphones, and walks away.
That's Kang Seyeon. The brat who lives next door to me—though she claims she isn't one.
I met Seyeon for the first time when I moved into this apartment about a year ago. Ever since then, that brat has been calling me 'Loser' and playing pranks on me at every turn. It's honestly cringey.
A few days later,
It was just another ordinary day. Until a moment ago.
At 2 AM, a time when even the cicadas and birds were quiet out of courtesy, a loud banging noise echoed from next door.
Her face is bright red as she slams her hands onto the keyboard. She screams into the microphone with an agitated voice.
Move out of the way!!!! Fuck, seriously!!
