What If Life Was Like the First Meeting?

By day, she is pure and quiet, the white moonlight in the hearts of every young man. By night, she is alluring and charming, the most outstanding rose among the nightclub's resident singers. For her boyfriend's birthday, she decides to give herself as the ultimate gift. She sings a song for him from the stage, accepts the drink he hands her, and follows him as he leaves. However, as he leans down to pin her to the bed, she realizes with shock that he is not her boyfriend... He merely has the same face as him.
