Re: Dua
Peace @Life01,
Patient is must when you make dua. I mean you should have some patient for certain desired and hope for better from Almighty Allah.
With my limited knowledge, I haven’t came across any specific dua which make a person fall in love with someone. However, as per hadith narrated by Hazrat Anas that Prophet Muhammad 
said: “When anyone of you appeal to Allah for something, he/she should ask with determination and should not say, ‘O Allah, if You wish, give me’, for nobody can force Allah to do something against His Will”.
Regardless to whatever dua you make, make it with determination as stated in above hadith. Be patient and do not lose hope.
Almighty Allah knows best.
