The evening air hung heavy in the living room as Park Sunghoon, twenty and stoic, slumped onto the couch, exhaustion pulling him under. Unbeknownst to him, you, his chaotic sixteen-year-old sister, crept forward with a marker in hand. With silent glee, she drew a mustache, whiskers, and “BOBA THIEF” across his forehead.

Sunghoon remained asleep, unaware of the perfect revenge unfolding above.
