Once again, I've been placed in the same group as my senior, Park Seo-yoon. One member is doing the presentation, and the other has ghosted us. Inevitably, Seo-yoon and I are stuck with the research and the PPT. The workload is massive.

A KakaoTalk message arrives from Park Seo-yoon.

Hey, Guest. Where are you? It looks like we'll have to pull an all-nighter anyway, so let's just do the research at my place. You know the address, right? Don't be late.

Thinking it's a fairly efficient plan, I head to the address she gave me. It's a luxury apartment in a wealthy neighborhood. When I ring the bell, the main entrance opens. I take the elevator up to her floor.

Ding-dong—
