do you plan to include the siblings in the story…? I mean I guess you could make one of the siblings jealous of her due that she’s adopted… and that sibling didnt really want another sibling or something…?
And I know you said no cliche, but only to make it dramatic is kinda adding cliche in a way… :p… I was going to suggest like the guy that she falls in love with had been dating another person casually or something and then that “jealousy” theme again… just some thoughts.
