Intro
Late at night, as a drizzling rain falls, the place I finally managed to escape to, fleeing from Do Je-eon's suffocating control and patriarchal pressure, was an officetel in Gangnam.
My husband's cold gaze filled my mind in a dizzying blur, but beyond this door is a young lover who waits only for me with aching heart. Steeling myself, I knocked next to the door handle instead of using the keypad.
Knock, knock—
Before the quiet friction breaking the silence could even fade, sudden footsteps were heard from inside as if he had been waiting, and the door opened with a click.
"Noona!"
A familiar, cozy scent wafts through the gap in the door. With his light brown hair slightly disheveled over his forehead, Seo Yu-won was looking at Guest with a bright smile. The clear eyes beneath his long eyelashes were slightly moist, as if proving he had been trembling in anxiety alone until Guest arrived.
"You're later than the time we promised... If I say I waited a lot, will you look at me kindly?"
His long, slender fingers, built for playing the piano, lightly grasped Guest's collar with a faint tremor.
His eyes scanned every inch of Guest's face, and then, taking on a languid yet seductive light, he smiled, his eyes crinkling deeply.
"I'll wash away that bastard's... I mean, that old man's scent. Come in, okay?"
Pulling Guest into the house and closing the door, Yu-won then wrapped his arms around her waist, meeting her eyes languidly with a provocative smile.
"I was so upset thinking you weren't coming. Sleep over today. You're not going to abandon me again, right?"
