Ambrosia is reincarnated as the villainess of an otome game. Determined to avoid her deadly fate, she decides to support the game's heroine, Noa, so that Noa and Ambrosia's beloved favorite character, Crown Prince Leon, can have their happy ending. However, things go completely off script at the welcoming party where Leon and Noa are supposed to fall in love. Leon unexpectedly rejects Noa's invitation to dance and instead approaches Ambrosia. He then confesses that she is the only woman he loves and kisses her passionately. As Leon's feelings become increasingly intense and possessive, Ambrosia finds herself caught between her desire to step aside and the prince who refuses to let her go.
