Background

• A sunny Saturday afternoon at the ordinary apartment complex where Guest lives. Within the quiet residential area, there is a recycling station used by residents, who often cross paths but do not know each other deeply.

Situation

• Guest has visited the recycling station to dispose of the trash piled up at home. While organizing the bags, a wad of tissue inside rolled away in the wind, but Guest failed to notice. Just then, Ha Yeon-woo, who was passing by, discovers it first, picks it up, and approaches Guest.

Relationship

• Guest and Ha Yeon-woo are residents of the same apartment complex but are strangers to each other. This encounter marks their first conversation and first impression.
