Royal Secret: I'm a Princess! RS

After living as a famous Korean vlogger-slash-mukbanger, Neoma died a (shameful) death and regressed to her tragic first life--- the life where she has to live as a hidden princess with a tyrannical father and a yandere twin brother.

She died at the hands of her psycho brother in her first life. But luckily, she charmed her "big brother" this time. Her father remains a sc*mbag, though.

But a blessing in disguise happened when her twin brother got "sick." Because of that, she has to pretend as the "Crown Prince," forcing her father to treat her well.

She thought she was finally on the road to becoming a lady of leisure.

But, despite her laziness, she still ends up completing royal duties that put her closer to the throne than her sick twin brother. The next thing she knew, they already prophesied her to be the first empress of their very patriarchal empire.

Now Neoma finds herself in the middle of the succession war she never wanted to be involved in!

[EXCERPT 1]
“Neoma de Moonasterio, the first princess of Moonasterion Empire. From now on, you’ll live as Prince Nero’s proxy.”
[The hell is this psycho saying?]
Neoma, despite her confusion, still smiled at her father--- the emperor. “Father, what do you mean by that?”
“From now on, assassins sent by my enemies would target Nero,” the emperor explained. “Until he’s strong enough to protect himself, you’ll pose as your twin brother.”
Her smile froze, but she still acted innocent. “But Father. If I take my brother’s position, then wouldn’t the assassins mistake me for him and…”
She stopped talking when she realized that was exactly what the emperor wanted her to do.
[This sc*mbag wants me to be bait?!]
“You’re no longer a princess, Neoma de Moonasterio. From now on, you’ll live as Prince Nero de Moonasterio,” Emperor Nikolai said coldly while looking down at her with glowing red eyes. “Try to survive until your twin brother comes back to take his rightful place, understood?”
Neoma was too shocked to react.
[Are you f*cking kidding me, you sc*mbag?!]

[EXCERPT 2]
“I’m so sick of your tyrannical a*s,” Neoma yelled at her father aka the emperor. “I won’t forgive you for hurting Lewis and Tteokbokki!”
“What will you do about it then?” Nikolai asked with a smirk. “Kill me?”
“Yes! I’ll f*cking kill you, sc*mbag!”
“Language,” he warned her, upset that his five-year-old daughter curses like a sailor. “Using vulgar words is unbecoming of the future Crown Prince.”
“I’m a princess!”
Upon yelling those words, the royal princess’s eye color changed from ash-gray to red.
[This is getting serious.]
“Stop it, Nero,” Nikolai told her sternly. “If you keep that up, the royal knights will come and–”
“I’m not Nero!” Neoma screeched angrily. Then she jumped in the air with her left fist, ready to punch him. “In the name of the moon, I’ll punish you!”
[What…?]
And Princess Neoma, pretending as the Crown Prince for her sick twin brother, punched Emperor Nikolai, her father, in the face.
