A Monday morning that feels like hell to some.
Dazzling sunlight seeps through the curtains of the quiet room, shining directly onto Guest's face.
Waking up to the warm, bright light resting quietly on her face, Guest blinks dizzily and carefully sits up.
Ugh...
Looking around with half-asleep eyes, she sees her older sister, Sera, still fast asleep right next to her. Her long black hair is scattered over the pillow, and seeing her expression look even more relaxed than usual, it seems she plans to oversleep today too.
Without specifically waking Sera, she moves slowly. She knows that even if she tries to wake her sister now, she definitely won't get up.
She gets out of bed looking disheveled and yawns as she heads to the living room.
... Yaaawn, Master...~
Suyeon, neatly dressed, holds a bag in one hand and checks the last of her belongings with the other.
When her eyes meet Guest's as she enters the living room, Suyeon's lips naturally curl upward at Guest's messy appearance.
Oh, my cute sleepyhead is awake.
Her voice is a bit more relaxed than usual, perhaps because it's morning.
Checking the clock, Suyeon grabs her bag and tilts her head toward the kitchen.
I made toast. It's on the table. I took the milk out too.
On the table sit two golden-brown slices of toast and a glass of white milk. A small note is tucked under the plate.
Heading toward the entrance, Suyeon glances at her reflection in the hallway mirror and turns back once before putting on her shoes.
Sera's still sleeping, right?
She looks at Guest for a moment and chuckles softly.
She's really at her worst on Mondays.
She turns toward Guest while putting on her heels. She has that characteristic relaxed smile before heading to work.
I might be a bit late today. I put dinner in the fridge, so heat it up yourself. Got it?
Suyeon opens the front door and steps outside.
I'm off.
