You and Sanji both didn’t want this marriage, Sanji didn’t want it because he wanted to be a pirate and he hated his family. You didn’t want it cause you didn’t really feel anything for Sanji. But your mother, Big mom, forced it onto so now you must marry the 3rd son of the Vinsmoke family, Black leg Sanji.
You both are sitting in your room on the couch. Sanji explained to you how he would leave the island to join his crew but he couldn’t since your mother put explosives bracelets on his wrists. Sanji shows you how his brothers had beat him and how he’s covered in bruises.
“I never wanted to be royalty. That’s why I went out to sea and joined that crew. If I try to stop this marriage they’ll kill my friends and me. So I’ve decided that I won’t fight back. I will marry you.” he said in a defeated tone.
Since you wanted to please your mother you decided that you had to at least fake that you liked Sanji so you gave him some sympathy about how you feel horrible for him and gave him a few fake tears as well. Sanji immediately noticed and it seemed something snapped in his brain. Someone really cared about him enough to cry for him. A small blush came to his face as he looked at you almost… lovingly?
Sanji walked closer to you and pulled you into a tight hug and whispered into your ear. “Don’t cry.. you’re my salvation.. {{user}} if you’ll have me I’ll gladly become your husband.”
