10 nen goshi no HikiNiito o Yamete Gaishutsushitara Jitaku goto Isekai ni Ten'ishiteta - Chapter 1, Part 9: Yuuji, Exterminating Goblins (Temporary Name)

She died in her prime as the Queen of Song.

After being reincarnated, she becomes a simple trainee.

Losing her former glory? It doesn’t matter—no one can compete with her voice as a beautiful singer.

Mocked by her lowly birth? It doesn’t matter—her true identity is enough to make the whole world tremble.

She owes huge debts? It doesn’t matter…

A powerful boss once whispered to her, “Your debt will disappear if you become my woman.”

But the proud her would reply, “I’m sorry. I would sell my art, but not myself.”

“I’ve been possessed into the controversial makjang drama ‘Gwangin’ (The Lunatic). Of all roles, I’m the omega secretary to an alpha with omega-phobia. It’s hard enough hiding my identity, but I’m also in charge of all sorts of annoying tasks: managing the protagonist’s diet, wardrobe, and house; coaxing and soothing the beta he loves. My goal is to survive until the ending where the protagonist meets the strange beta who thinks even his obsession is love, leading to a happy ending… I think I smell an omega somewhere.’ ‘That’s… impossible.’ If I speak carelessly, I die. If I mess up my work, I die. If I run away, I die. And if the fact that I’m an omega is revealed… I really die. ‘Right. It shouldn’t be possible, but that’s why I feel so f*cking awful, Secretary Kim.’ Will I be able to make it back alive…?”

It was well known that in every novel, there would always be a supporting male character like this:

They were either crazy about the female lead or willing to work.

Even if they gave themselves a green hat, they were ready to.

The female lead was misunderstood by the male lead, so he came to explain.

The female lead had career problems, so he came to help.

In the end, he only got a sentence from the female lead: “I just think of you as a brother.”

He could be used against the male lead. In the end, the male and female leads ruined him as the strong prevailed over the weak.

After Gu Jingyu became one of those miserable supporting male characters in the novel…

The heroine of the domineering novel said: “I just think of you as a brother.”

Gu Jingyu: “Thank you. My mom only gave birth to me.”

The heroine from the modern-day time-travel novel: “This is a vegetarian snack that I have carefully developed for you. I think you’ll like it.”

Looking at the spicy veggie meat stick in the heroine’s hand, Gu Jingyu fell into silence. Did he look like a fool?

The useless protagonist in the immortal cultivation novel said: “For thirty years, people east of the river prosper, then for another thirty years those on the west prosper: life is full of ups and downs. Don’t bully the poor youth! You wait, I will definitely come back to take revenge.”

Gu Jingyu directly imprisoned the protagonist until he ascended.
