Nope it doesn't . Cast doesn't make a big difference if you love some one . But issues can occur only in cases where
a)One person asks the other person to give up his religon and convert.
b) The lover shows any kind of disrespect towards the other persons religon OR does not allow him/ her to practise her traditions freely.
As long as you respect each others religon you will not have an issue.
if ur in love it shouldn't matter 2 u what cast r they.
u fell in love with he/she so accept them the way they r.
families do get involve with this matter but at least 98% wouldn't agree 2 the realtionship and 2% would agree 2 it
frm personal experiance i wud say different caste makes a big difference and mst famalies jst dnt expept it especially if its a different religion and caste becomes hard 4 boths loverz is kinda sad da way society finks
I think caste doesn't matter in love itself, but when matters come to family, it makes a hugeee difference because the lovers just fall for each other without any considerations, ubt it's the parents who really differentiate between caste and all that stuff. So in a way, it does matter
