Shh, Princess, He's an Incubus [Western Fantasy]

[The blurb has been screenshotted]

Question: What's it like to be the most beloved princess in the temple?

Su En (raising her hand): The Elf King is secretly in love with me and gave me his heart's blood to grant me a gift. The Holy Angel adores me and blesses me every day. My cousin from the Dragon Clan cherishes me and gave me his entire treasure hoard, along with his protective scales.

I'm beautiful and kind, innocent and delicate. I can't bear to hurt my admirers, so I accept everyone who comes my way... and their gifts.

I'm the temple's cherished darling. If I really were a princess, I'd have a carefree life.

But

I'm a bug fixer in an infinite-flow world. In this world, my character is a succubus. Now that the bug has been fixed, I'm about to leave.

Before I go, I've decided to have one last wild time:

Kidnap the Elf King, blindfold him, and put on a show of a succubus bullying a princess right in front of him.

Invite the Holy Angel out, reveal my long-suppressed bratty side, humiliate him thoroughly, and mock him for thinking an ugly duckling like him could win a swan's love.

Then follow my cousin from the Dragon Clan to the bathroom, stand beside him, hike up my puffy princess dress, pull out my buddy, and compare our range. Oh, I really did scare him into missing!

Prank successfully pulled off. I'm out of here!

Su En (biting a handkerchief): Help! The bug wasn't fixed after all. I can't go back!!

Reader's guide:

1. The main story is told in third person.

2. The love interest initially disguises himself as a woman.
