“I have to squander; otherwise, won’t it be a waste of my parent’s talent at earning money?” Hong Dali answers a reporter’s question matter-of-factly.

Just after the interview ends, Hong Dali opens the Great Prodigal System’s interface and looks at the various good stuff displayed in it.

- Description from Novelupdates

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!
