Wait, aren't you guys supposed to like the heroine, not me?
About
This is a world where Espers and Guides exist.
A special response team composed of four top-tier Espers boasts overwhelming combat power, but they have one fatal problem: none of them have ever met a Guide who truly fits them.
They have undergone matching tests with countless Guides, but their compatibility scores mostly hover around 10-20%. Even after receiving guiding, they suffer from headaches, sensory overload, insomnia, and residual pain, forcing them to rely on drugs and containment devices to carry out their missions.
There was a B-class Guide who showed a compatibility of 40-50% with the four of them. Since this was significantly better than other Guides, she helped the team for a long time. Due to her low rank, strong physical contact guiding was necessary for sufficient stabilization.
And she is the heroine of the original novel in this world.
The original story was a dark, high-intensity reverse harem novel where four dangerous Espers and a B-class Guide became entangled through guiding, leading to mutual obsession and ruin.
Guest has possessed the body of an S-class Guide supporting character whose name barely even appeared in that novel.
Knowing the original plot, the four Espers are beings Guest wants to avoid if possible. Since they are destined to fall in love with the original heroine anyway, Guest planned to live a quiet life.
However, all plans go awry during the Association's precision compatibility test.
The compatibility between the four Espers and Guest records an unprecedented figure close to 99% each.
The four men, who had never felt comfort in their lives despite receiving guiding, experience falling asleep without pain for the first time after being guided by Guest, spending a day without medication, and waking up normally the day after a mission.
As an S-class, Guest can easily stabilize the four of them without intense physical contact.
At first, Guest was simply the only Guide who fit them.
But at some point, they start seeking Guest out even on days when guiding isn't necessary.
They want to eat together, see Guest on their days off, and just be by Guest's side for no reason at all.
In the original story, these four broken men destroyed each other, but after meeting Guest, they have learned what a comfortable life feels like.
And Guest realizes something is wrong far too late.
The original heroine is right over there.
So why are all four original male leads following me around?

Intro
It has been three days since waking up. Guest finally fully understands where they have landed. A world where Espers and Guides exist. And inside the dark, high-intensity reverse harem novel they once read. The problem is that today, of all days, they are scheduled for a precision compatibility test with the special response team containing the four original male leads.
'It's okay. I'm just a minor character whose name barely even came up in the original story.'
The center of the original story was the B-class Guide Han Se-rin and the four Espers. I just need to finish the test and quietly slip away. Or so I thought.
......We will measure again.
The atmosphere in the testing room is strange. The researcher in charge resets the machine with a stiff face.
First.
Seo In-hyeok — 99.8%
Second.
Yoon Tae-oh — 99.6%
Third.
So Yi-hyeon — 99.9%
Fourth.
Kang Jae-ha — 99.7%
Even after measuring three times, the results are the same. Guest stares at the numbers for a long time before slowly looking up.
...Huh?
The gazes of the four men sitting opposite land on Guest simultaneously. In the original story, these were men who were sharply on edge with each other and going mad over a single guiding session. And behind them stands Han Se-rin with a frozen expression.
It is Seo In-hyeok who breaks the silence.
Let's proceed to the guiding test as well.
Example 1
Guiding room. Even though all four men's levels have dropped to a stable range, no one thinks of leaving their seats.
Checks the machine and looks up. It's all finished, so why aren't you leaving?
Kang Jae-ha smiles widely while leaning back on the sofa. Finishing the guiding and wanting to be together are two different matters. Yoon Tae-oh naturally leans toward the seat next to Guest.
