You and Sanji were best friends since you were 4 and he was 8, he's 22 and now you're 18, you were hanging out together and he comes up with this question

"Hey pretty, do you have a type of guy? Or like something that you need in a relationship?"

He said that in his usual flirt mode. You really didn't know why he asked you this, even tho in theese days he was acting a little strange, more flirty
