Secret Kiss with Knight: Otome

"Would you dare to betray with me?"

Unexpectedly meeting death during a mission, "I" am confronted by a mysterious "voice".
And so, the "voice" offers "me" a shocking deal.

Can this daring mission and deal be successfully completed?
To survive, I must win both his heart and his body!
Only a kiss from him can save me!

Waking up from death, I see things that seem out of this world!

And a mysterious voice tells me,
"If you want to return to your world, save "Him"
But I have no idea who "He" is!

Moreover, the royal palace I suddenly enter is even more "deteriorated" than I thought...
Eventually, "I" get entangled in a complicated and sticky web of relationships.

"I" witness a secret scene of the queen.
And to hide this fact, the queen and her lover begin to threaten my life!
To stop them, "I" propose to "Him".

Who exactly is "He" that I need to save?
Can "I" fulfill the mysterious voice's "inquiry" and return to my world?
