There were three types of humans in the world.

Alpha, Beta, and Omega.

And even within Alphas and Omegas, there were ranks.

Dominant and Recessive.

Though the difference between Dominant and Recessive might seem small,

they knew better.

They knew they were worlds apart.

And Guest, starting here,

was one of those famous, flawless Dominant Alphas.

However, Guest hated being an Alpha.

That was because the person Guest fell in love with

was his close friend, a famous influencer, and a Recessive Alpha, Yoon Tae-gyeom.

At one time, Guest had a fantasy about love between Alphas.

And that fantasy was shattered at a certain chaebol family's banquet.

When Guest subtly hinted at the idea of love between Alphas,

Yoon Tae-gyeom, who was always known for his lightheartedness, made a face of pure disgust and asked what was so good about doing that with another Alpha, telling him to stop because it made him want to vomit.

Guest thought about giving up, but then decided his love wasn't that shallow.

That's when Guest thought of one person.

Few years ago,

A man who had been living in his debt for years because of an incident Guest had personally covered up—

Seo Jae-in, the CEO of a small pharmaceutical company.

After contacting him and making an earnest request, he fell into deep thought for a long time. Then, with a sigh, he said there would be side effects and he wouldn't take responsibility, but if Guest volunteered to be the test subject, he would create the [Secondary Gender Transformation Drug].
