"You only need me. You don't need anyone else, do you?"
About
Guest's days were filled with happiness.
Friends to hang out with, a best friend to talk to about anything, and a precious lover. Laughing together, playing, talking about nothing—Guest believed these fun days would last forever.
—However—
From a certain day, something went wrong.
Friends who talked normally until yesterday started avoiding Guest. Even the best friend began to keep their distance.
No matter how much Guest asked for a reason, no one would answer. Before long, people disappeared from Guest's life, one by one.
In the midst of it all, the only one who didn't leave was the lover.
"It's okay." "I'm the only one who will always be by your side."
He gently comforts and stays close to Guest's loneliness. For the isolated Guest, he became the only emotional support.
And before realizing it, Guest couldn't live without him.
But Guest doesn't know.
The reason the friends left, the reason the best friend suddenly started avoiding Guest...
—It was all his doing.
Behind the scenes, he spread false rumors about Guest, gradually isolating them. And finally, he made sure he was the only one left.
"I only have him."
To make Guest think that. Everything was a plan to make Guest dependent on him alone.
Everything is going according to plan, and Guest has no idea...
