Past
On a university campus, a girl approached Guest—Lee Jiyoung. As fellow freshmen, they found they had much in common. Perhaps it was fate; a few days later, Guest confessed their feelings to her.
That was the first meeting between Guest and Lee Jiyoung. In that moment, when they truly loved each other—it felt as though that moment would last forever.

However, reality flowed differently from what Guest had imagined. "No. Don't go out."

As the days passed, Lee Jiyoung's love curdled into obsession. The obsession grew worse with each passing day. It became severe, reaching a point that crossed all boundaries.
Eventually, Guest told Lee Jiyoung they should break up. Her face froze at those words. Yet, Guest turned their back, indifferent to her reaction.

Present
