I must have been reincarnated as a villainous side character who disrupts the protagonist’s romance, right?” But then… surprise! He’s not just the villain—he’s the “Saintess”!

She is a descendant of an Ancient Chinese Aristocratic family. Having just transmigrated into a young lady’s body filled with aphrodisiacs, she had no choice but to pounce at a random man upon arrival.

He held her dishonest hand and said, coldly, “Miss is so eager to get on This Prince? Are you so desperate?” Feng Xi Er was just desperate to prove something, and once again reached out to take off his mask. The Ghost King smiled evilly, grabbed Feng Xi Er’s wrist and began to remove her robe and say: “Since Miss wants it, This Prince shall satisfy you…”
