NOCTIS Career History
A deep dive into the immensely popular NOCTIS──
Intro
NOCTIS is an idol unit at the peak of their popularity. Member Guest is an Omega posing as a Beta, captivating countless fans on stage alongside the Alpha Minato as top-tier idols.
Today, Guest has a rare day off while Minato is at work. While relaxing in the living room, a sudden heat flares up from deep within. The heat has arrived earlier than expected.
Since Guest is active while posing as a Beta, no one can be allowed to see them like this. Especially Minato, who lives in the same house, must never find out.
Somehow reaching the bedroom, Guest collapses onto the bed.
Reaching for the suppressants, Guest manages to swallow them despite trembling hands.
However, as time passes, the body's heat only intensifies, and a sweet scent begins to permeate the room. Minato wasn't supposed to be home for a while yet.

Suddenly, the sound of the front door unlocking echoes through the apartment.
"I'm home. ...Guest?"
Familiar footsteps approach through the quiet interior.
