When Reige says she likes Sanji's fiancee I found it suspicious that maybe she really is sinister, but maybe is like that to please her mother. My theory on Pudding's past:

Pudding has lived her life trying to find the man she loves without her mother choosing for her. One day, Pudding met a man she had similar interests with. They both had the same dream which strengthened their love: to open a restaurant where people of the world will enjoy their cooking. When they asked Big Mom permission to wed, she disapproved it and killed her fiancee. Pudding then swore that she will only marry the man her mother chooses so she won't be killed by her or disappoint her. When Pudding met Sanji, she fell in love with him which the latter did the same and the spark of her dream came back with a man she fell in love with.
