Ye Zhen, a female Ph.D. in the Department of Mathematics of Huada University, changed her career to enter the entertainment industry in order to investigate the death of her birth father, Film Emperor Ye Yi. During her interview, she accidentally made CEO Rong Cheng Jue lose face in public. Yet Rong Cheng Jue, unlike what was to be expected, didn’t take old grudges into account and let Ye Zhen join his company. When everyone thought Ye Zhen would become Rong Cheng Jue’s personal secretary, she actually joined the entertainment department. After several twists and turns, Ye Zhen became an errand reporter for Rongcheng Entertainment’s “Treasures of Great Tang”.

Her colleagues’ bullying towards her, the pressure of changing career, and the many obstacles in her investigation all left her confused. Under Rong Cheng Jue’s silent guardianship, she didn’t forget her original purpose, overcame every obstacle, and eventually became an ace producer.

Ye Zhen and Rong Cheng Jue shared a common belief : no matter how bleak the hope is, how thorny and dark is the road ahead, they had only one thought in their hearts: to uncover the truth, and therefore bring peace to the soul of the Film Emperor Ye Yi.

I became the fiancé of the tyrant male lead, a character who becomes a villainess because she was obsessed with the beautiful tyrant.

Of course, in the end, she was killed by the tyrant.

Still, this all happened before the original story began.

After diligently performing a dozen or so actions that would cause me to be dumped by him, I succeeded in becoming a sound friend of the tyrant, who turned out better than I had thought.

“How was it?” asked the female lead, who he saw for the first time.

“Hmm?”

“I meant your meeting with Miss Diel (female lead), Your Majesty.”

He tilted his head slightly. Hey, don’t pretend you aren’t interested.

It is said that he fell in love at first sight, but I saw it all.

Hehe. I chuckled and poked his arm with my finger.

“You know what? Please let me know if you have someone you like.”

“Why? So you can kill her?”

Heh, do you think I’m like you?

I smiled sincerely and answered him. “Well, I’ll break off our engagement at the right time.”

“Miss.”

The smile on his face disappeared in an instant.

I somehow became speechless after my gaze met his glaring eyes.

He stared at me and laughed quietly in a slightly husky voice. In a subdued voice, he then said, “Don’t make a joke like that.”

His hand stealthily and gently brushed off the strand of hair on my cheek.
