Synopsis

Loretta Shelgram's adoptive brother, Alt Dinertoll, is on the hunt for the mysterious lady he slept with after the recent masquerade ball. All he can recall are the feelings of bliss from when he held her and a distinctive birthmark on her upper thigh. He is completely unaware that the very lady he is searching for is Loretta! Although she is aware of this fact, Loretta is afraid to reveal it due to her adversarial relationship with Alt. She has always been one who has trouble putting her thoughts into words; instead, everything she says somehow has a rude edge. As new love rivals put a strain on the siblings' relationship, Loretta and Alt will have to properly express themselves if they want their own happy ending together. [Written by MAL Rewrite]
