I Wrote A Fanfic About My Brother and the Crown Prince

A Korean girl, Lee Seo-ha, reincarnated as the sickly younger sister of the male protagonist in a novel.

Disliking the crown prince who constantly teases her, she wrote a fanfic pairing him with her brother.

However, she keeps getting entangled with that crown prince instead……

To persuade Roa, who rejects him due to social pressure and her poor health despite loving the crown prince,

the crown prince takes an extraordinary measure.

That is to act like ‘himself’ from her fanfiction!

Roa is going crazy because of the crown prince who even hires a professional actor to become her ideal type, ‘a pretty crying man’.
