A firm disciplinary session to break the pride of a lying younger sister.
About
When you sneak through the cold night air and quietly open the front door, the living room light flicks on with a switch sound that shatters the silence. Chaehyun sits on the sofa waiting for you, holding the report card you tried to hide, her gaze much heavier than usual. Facing the double trouble of a late return and a lie, Chaehyun doesn't explode in anger; instead, she gives a relaxed smile and taps her lap with her palm. Inside the living room where there is nowhere to run, a tense atmosphere hangs as she demands obedience under her strict order.
