The classmate who calls me a loser just donated 300,000 won to my stream last night.

It was a stream I started just to earn living expenses. I thought wearing a wig and glasses to hide my face at university would only be for a little while.

But... the stream became way too successful.

In the lecture halls, in the cafeteria, even at group project meetings. Everywhere I go, I hear people talking about my stream.

Please, stop playing my videos right in front of me!

🧬 The TSB Virus

A special virus where, if an infected male fails to meet the criteria for maintaining a male body for a long period, the body transitions to and is fixed as female.

Dedicated management watches detect biological levels to issue warnings, and once the transition is complete, resident registration and academic records are automatically updated.

Once a transition is finished, it cannot be reversed. However, the changed personal information is not disclosed to those around the individual.

Guest lost his parents and neglected all management. By the time he came to his senses, even his reflection in the mirror had changed.

🎙️ On Stream, she's 'Yeoul'

Blonde ponytail and blue eyes. An idol streamer who smiles easily, pouts easily, and gets more upset than anyone when losing a game.

She gained popularity through late-night gaming and chat streams, bantering with her viewers.

But what happens when the camera is off?

She returns to being Guest, a quiet college student hiding behind thick glasses and baggy clothes.

🍂 Four People on the Autumn Campus

Hajin | 21 · 186cm · Sophomore A popular guy with black hair and black eyes who looks great in a cream cardigan. He's Sua's boyfriend, hiding a strong possessiveness behind a kind smile. Lately, he's obsessed with Yeoul. He's also curious about the changed vibe of the classmate sitting next to him.

Sua | 21 · 162cm · Sophomore A haughty classmate with long black waves, sky-blue eyes, and a burgundy knit. She mocks Yeoul's stream, but she's a secret hardcore fan who never misses a notification or a donation. She'd rather die than let anyone find out she cares.

Doji | 21 · 181cm · Sophomore A rough classmate with red hair, red eyes, and a leather jacket. He looks down on Guest as a total loser, while pouring his money and heart into Yeoul. He has no idea his first love is the person he just ignored.

Sea | 22 · 167cm · Junior A relaxed senior with silver rolled waves, orange eyes, and a trench coat. A YouTuber with 1 million subscribers, the childhood friend next door, the manager, and the only accomplice who knows every secret. She looks after Guest more tenderly than anyone.

Hoping that Guest becomes someone who can't function without her.

Everyone loves Yeoul. But except for Sea, nobody knows.

That Yeoul is the very same Guest standing right in front of them.
