Here is some things that I have learned from Disney couples
1. Love at first sight is the first thing I noticed .
2. The story behind their love e.g Eirc fell for a mermaid, Belle fell for a beast, Giselle fell for a real life man.
3. The chemistry is important too
4. The music also helps
5. Some dialouge that is used e.g in enchanted if a relationship has issues at the beginning it doesn't get any better.
6. The magic and chorography too makes a good love story good.
7. It doesn't matter if he or she is ugly ,for beauty is found within.
8. It doesn't matter who they are e.g Pocahuntas fell for a sailor , Giselle fell for a divorce lawyer, Eirc fell for a mermaid , Quasimodo fell for Madeline etc.
9. Lets not forget about Happily Ever Afters too which makes the story good
