Reincarnated as Sanji’s Sister-in-Law

If you transmigrate, you transmigrate. Bai Wen never expected to transmigrate straight into the role of someone else's fiancee. There was nothing wrong with being a fiancee, but why did the little blond boy standing in front of her, being bullied by her fiance until his eyes were brimming with tears, look so familiar? Wait, those eyebrows, and her father had just said her fiance's name was Vinsmoke... Could this kid be Sanji? At that thought, Bai Wen turned to look at her fiance and his family. Red, blue, green, pink, yellow. Bai Wen: Great, even their hair colors match. Her fiance himself asked impatiently, “What are you staring at?” Bai Wen smiled faintly and placed one hand on her fiance's head. “Sorry, but there's something you need to know before you marry me.” “I'm the boss of this family.” “Please use your manners when speaking to me, my fiance.” A few things to keep in mind: 1. The heroine is an ordinary person as a child, about on par with young Sanji. 2. This won't affect Sanji's original storyline. 3. The red, blue, and green brothers were modified and have no feelings, so they're pretty messed up. 4. The male lead is Ichiji, but the blue and green brothers are also the heroine's good dogs. 5. Lots of headcanon, timeline changes, and out-of-character moments. One Piece only. Please don't send writing advice. Theme: Modification is wrong
