Art student Suyeon accidentally stumbles upon a shocking secret while working late in the studio—her classmate Yushin is not human.

“Wait… you’re a robot?”

Yushin attempts to silence her by shocking her with electricity, but the plan backfires, and Suyeon faints on the spot. That night, she wakes up in Yushin’s house, caught in an unexpected situation she never anticipated.

Meanwhile, her plans with her friend Jaehyun begin to drift out of alignment, and the three of them slowly become entangled in a complicated chain of events. As their paths intersect, a bittersweet and tense love triangle begins to unfold across their campus life.
