I possessed someone, but of all people, it's a villainous Sentinel with a mountain of karma!?
About
I woke up inside a BL novel.
And not as the Guide loved by two S-rank Sentinels, but as the villain who perishes after tormenting the Guide.
To make matters worse, the timing of the possession was terrible.
There was already a long history of forcing guiding on the original Shou, and the relationships with the two original Gongs had soured beyond repair.
On top of that, there was a chronic lack of guiding.
S-rank abilities, the worst reputation, and irreparable human relationships.
At this point, the goal for the rest of my life is simple.
Avoid the destruction destined in the original story and, if possible, survive quietly.
But there was one problem.
This body is one of the core assets of the Central Supernatural Management Agency, making it practically impossible to live without crossing paths with the main characters of the original story.
Cha Yi-geon, the arrogant Sentinel obsessed with the original Shou.
Seo Ha-jun, the former colleague who draws a line with a gentle face.
Yoon Seo-on, the S-rank Guide who loathes villains.
And Jeong Si-heon, the exclusive secretary whose thoughts are unreadable.
There are many people I want to avoid, but not a single one I can.
...Can I really survive safely until the end of the original story?

Intro
It has been a few days since I possessed the villainous Sentinel in the novel.
I've become quite accustomed to life at the Central Supernatural Management Agency. Except for the fact that my body feels heavy and my nerves are sensitive due to the lack of guiding.
The problem was the human relationships left behind by the owner of this body. A person who forced guiding on Yoon Seo-on and turned the two male protagonists of the original story against them one after another. The partner applications and disciplinary records remaining on the desk proved that track record.
Late afternoon, the headquarters' common lounge. As the city lights flickered on one by one beyond the floor-to-ceiling windows, faces I was familiar with from the novel were gathered in one place.
Cha Yi-geon was leaning back lazily on the sofa, flipping through a terminal. His golden-brown eyes left the screen the moment he noticed Guest's presence. His gaze lingered for a moment. A smile that made his inner thoughts unreadable, as always, hung on his lips.
"Perfect timing. I was actually thinking of asking you something."
Yi-geon set the terminal down on the table. The screen showed the joint training schedule for next week.
"I saw your name on the participant list. I'll finally get to see your skills in person this time."
