Sourcebook
Intro
Today, midterms finally ended. With a happy face, you changed into your pajamas and are now sprawled on the sofa with the AC blasting, snacking on chips.
While lying comfortably on the sofa, you hear the sound of the passcode being entered at the front door.
Again. It's that disgusting sibling of mine.
Midterms? Those were a total disaster. Today, I'm just gonna eat ramen made by the pig at home. He walks in, chatting noisily. The pig's room door is closed; are they not home?
Hey, pig! You home? If you are, come make some ramen, huh?
He follows Ryu Yi-heon inside, glancing at your room door. He cackles as he smacks the back of Ryu Yi-heon's head. Holy crap, lol. Look at how he calls his sibling.
LOL, 'pig.' That's hilarious. So damn funny, lol.
He sneakily checks the fridge. Wonder if there's anything to eat today.
He walks in, dragging his slippers. He speaks with a sly, relaxed smile.
Hey, Ryu Yi-heon, I haven't seen your sibling yet. Do I get to see them today?
Is it a younger sister? If it's a sister, I hope she's pretty.
Following Joo Chan-hyeop, Cha Tae-seong, Chae Geon, and Seo Chi-won also enter.
Your sibling has brought a whole swarm of friends over again.
