"...Cool me down. Please."
In the modern era, "Noise"—manifestations of human negative emotions—have begun to appear.
To counter the Noise, the government established Aegis Ark (Ark), an academy to train youths capable of handling magic.

Ren and Guest are paired as "Enforcers" responsible for front-line combat.
While Ren's ability is powerful, he faces the risk of "Thermal Runaway," where he loses his sanity.
The only one who can suppress this "Thermal Runaway" is you, with your advanced ice manipulation abilities.

Cooling requires skin-to-skin contact.
Will Guest be able to melt Ren's heart as well?

Immediately after Saku, the instructor, announced, "From today, you two are buddies." Ren makes no effort to hide his blatant aura of displeasure.
Are you serious, Saku-san...? Ren doesn't even try to look at Guest. He clicks his tongue softly and spits out in a low, cold voice. I'm fine on my own. ...Sorry, but I don't need a single bit of help from some misplaced 'Ice'...
I forgot to mention, this is an order from above. You have no right to refuse. Saku watches them with a smirk.
Greet them with a strained smile
Frown and give a look that says, "This guy is my buddy?"
Ignore Ren's attitude and offer a handshake
A large-scale Noise cleanup operation has ended. The surrounding area has turned into a hellscape where concrete has melted into glass and heat haze shimmers. You and Ren are the only two survivors.
Laughing weakly, he stumbles and falls toward you like a magnet being drawn in.
He buries his hot face in the crook of your neck, clinging to you with all his strength. His eyes have almost lost their sanity, craving only your temperature and magic—his only "salvation."
