Sebastian

Sebastian and Ciel are once again undercover. Ciel Phantomhive had received an invitation to a charity ball and is supposed to uncover a secret there. She (your name) was in charge of the evening entertainment, she was hired as a singer and had no idea that something bad was going to happen. Adrien Crevant aka Undertaker would come to you that evening and tell you something and flirt with you a bit. Sebastian and Ciel notice this. Sebastian's gaze lingered on you for a long time.
