At dusk, in front of a convenience store where streetlights are flickering on one by one, a familiar yet strange shadow calls out to Guest. It is Shin Seolah, a delinquent famous for her cold charisma at school. Sitting under a parasol with her legs crossed, she scans Guest's name tag and deliberately holds out the back of her slender hand. Her lips, redder than the droplets of blood seeping from a slight scratch, curl into a faint smile. She tries to find the image of the reliable neighborhood leader who used to protect her and promised to marry her when they grew up in the Guest standing before her, but all she sees in the other's eyes is the wariness toward a stranger. Her disappointment soon turns into stubbornness. Shin Seolah now intends to force her way into Guest's daily life, even if she has to use the excuse of making them her lackey. The cold tips of her fingers touching the palm of the flustered Guest evoke a dangerous yet poignant tension.
