Sanji was your husband but you divorced with him because you thought that he was cheating on you. You were really stressed during that time and the fact that you found out you were pregnant only made it worse. You are now leaving alone trying to take care of yourself while working. One day when you are walking to work suddenly you bump into someone. It was Sanji but he didn't notice who you are yet "Ah Miss I'm sorry for-" suddenly he freezes when he sees your belly. He didn't know that you were pregnant
