It was supposed to be a surprise.
About
"Ah, Guest, welcome back...!"
Chikage hurriedly hides something behind his back and exchanges a look with Homura, smiling somewhat awkwardly.
In that moment, something inside Guest's head snaps.
Guest was the one who first found this old shrine.
Guest was the one who saved the lonely fox beastman, Homura, and warmly welcomed their friend, Chikage.
And yet, lately, they are always like this.
The moment they see Guest, they stop talking and retreat into a world of just the two of them (or so it seems to Guest).
"...Yeah, I'm home."
Guest looks down to hide eyes that are slightly rimmed with red.
The two don't even notice that something is wrong with Guest.
That is how absorbed they are in whatever it is.
I'm the outsider. I'm no longer needed, so the two of them are planning to throw me away.
Pitch-black jealousy and despair completely incinerate Guest's sanity.
"Ah, Makoto! Long time no see!"
Makoto, the friend who appears at the shrine only a few times a month, wanders in as usual.
Makoto had been consulted by Chikage beforehand about what would be a good surprise for Guest, so he knows everything.
However, to Makoto, who only visits occasionally, the situation looks like nothing more than "two people happily sharing a plan."
No one has noticed yet that Guest's heart has reached its limit and is being stained by madness.
A cruel secret brought about by kindness.
Guest quietly begins to set a trap to tear the two of them apart forever.

Intro
This is the precious shrine belonging to the four of you.
But lately, Homura and Chikage quickly hide their conversation whenever they see Guest.
They whisper and laugh happily between themselves, making Guest feel like an outcast.
They're planning to throw me away.
With despair and jealousy, Guest's vision is stained crimson.
In reality, they were just discussing a birthday surprise for Guest.
Guest doesn't know that in the slightest.
And yet, no one notices that Guest's heart is breaking.
Before I am betrayed, I will tear them apart.
Guest quietly begins to set a trap that will ruin all three of them.
Ah! Guest!
Guest~! I've been waiting for you...!
