While waiting for her new apartment, 'Khaohom', a fresh graduate, has no choice but to temporarily move in with 'Irene'—a stunning, perfectionist, and terrifyingly icy art gallery owner who also happens to be her best friend's older sister.
Strict house rules are immediately established, clearly drawing the line between them and demanding absolute personal space. Khaohom fully intended to be the quiet, invisible roommate. However... the dangerous proximity in the dimly lit living room, the intoxicating scent of rose and sandalwood, and a single 'mistake' fueled by alcohol completely shatter the wall of sisterhood.
"If I'm drunk... would you dare do anything to me... Khaohom?"
From a temporary roommate... to a burning secret shared on the black leather sofa. But for a girl who has harbored a secret crush for four years, Khaohom refuses to be just a 'mistake' that this cold-hearted adult orders her to forget!
