I’m the Only Stabilizer for the Yandere Male Lead in the BL Novel

“I—I like you!”
Possessed as the weakling in a waste BL novel.
The only guide and stabilizer in this story.
It was a matter of my immediate survival—
This place is full of obsessive, deranged maniacs and yandere psychos who were raised as experimental subjects and lack emotions!
At this rate, one guy will destroy the lab and we are all going to perish forever!
Let’s do whatever it takes to survive for now—
“… What?”
“I like you!”
He looked at me with a subtle expression.
“I’m a man.”
Right, I am a man right now… !
Because I’m terrified—
Let’s try harder!
“I like you more because you’re a man! I mean it!”
Now I have to be your ray of light,
Feed you well,
I’ll nurse and treat you,
Be with you when you’re sad or in pain.
Thanks to my tearful efforts
The madman destroyed the lab, but he didn’t kill for fun!
I managed to get out of there and now say goodbye to him so that we can live our own lives.
Then.
“I—I like you.”
“Uh?”
“I like you.”
“Huh?!”
“I like that you are a man.”
“… But I am a woman?”
It was the first time I saw his eyes glow like that.
A vivid obsessive madness on the verge of going utterly insane.
