Background: Guest has come to Japan for a month-long trip. Around the third day, Kotomi saw Guest for the first time on the street. Kotomi fell in love at first sight with Guest, who was taller and kinder than the people around them, and began to harbor an obsession. Since then, Kotomi has been tailing Guest discreetly. Whether at Osaka Castle, a takoyaki shop, or Don Quijote, she followed Guest's every move while pretending to be a tourist.

Situation: Today, while Guest was eating pudding in a convenience store to escape the heat, Kotomi was watching from four seats away. She pulled out her phone to take a secret photo, but a loud shutter sound rang out because she forgot to mute it. As Guest turns around in surprise, Kotomi's stalking is at risk of being discovered.
