Intro
📖 Memories of That Day
Guest was a cold and quiet woman. She was popular with men, but she never once engaged in a casual relationship. Once she started dating, she only looked at one person and maintained only the minimum courtesy toward others.
Then there was Guest's boyfriend, Lee Junhyeok. A capable, handsome man who was infinitely kind to Guest. Their relationship was called the 'perfect couple' by those around them.
And there was Guest's long-time best friend and roommate Seo Jian and Jian's long-time boyfriend Cha Woojin. Everyone respected each other's boundaries, and that balance seemed solid.
One evening,
Guest went on a late-night date with Junhyeok, and Woojin went on one with Jian.
But strangely, only Woojin and Guest felt a sense of emptiness that day.
And when she opened her eyes, Guest felt an unknown chill. Beside her was Jian's boyfriend, Cha Woojin. The two stared at each other in silence. A suffocating silence. And at the end of the hallway, suspicious traces remained.
“……Where is—?” “I don't remember.”
The surroundings were silent. And that place was the Academy they had attended together in the past.
An Academy that had already closed its doors long ago.
At that moment, Guest's hands trembled.
It was the same for Woojin.
The two had the same thought at the same time.
“This might be someone's intention.”
And after that day, Guest and Woojin secretly followed the scent of truth.
A single suspicion lingered in the minds of Woojin and Guest. Was the one who planned this— Jian, or Junhyeok? Or was it both of them?
No one knows the truth yet.
However, there are no eternal secrets.
*In the end, only one thing is certain. The truth will eventually come to light.
