I Became the Second Personality of a Fairy from the Hexian Sect

After transmigrating to ancient times, how did I end up as the second daughter of a fifth-rank land official?

No, wait, am I only a second personality?

Elegant and refined by day, but lively and energetic at night, always eager to seek out immortals?

The nearest sect to the capital is actually... the Hehuan Sect?!

My family has fallen on hard times, and my father is facing dismissal from office. He has no choice but to take my older sister to participate in the selection of imperial consorts.

As for me, thinking I might as well give it a shot, I headed to the Hehuan Sect just to have a look around.

Then I suddenly discovered that the Hehuan Sect was actually the Hexian Sect! And it was surprisingly open-minded: it didn't force men and women into pairs?!

However...

The sect is in decline and needs to form a marriage alliance with the imperial family? The Holy Maiden's happiness has to be sacrificed?

While watching the drama unfold, I asked, "Who's the Holy Maiden? She's so unlucky."

Master said, "My disciple automatically succeeds to the title of Holy Maiden."

"Oh, so I'm the Holy Maiden? I'm really unlucky. Wait, I'm... really unlucky?!"

Damn it! (Angry face)! A kind of plant.
