To answer first question:
Yes, same as arranged marriage.
To answer second question:
Love without knowing each other? Door Door Ka Pyaar does not really exist. It is something over-rated or just a myth.
Love is not something which occurs at first sight as is written at so many places! Now, with time this may grow on to real love.
Otherwise, it is infatuation and opposite hormonal attraction…like a bull jumping over the 6 feet high fence to get close to cows on other side!
That is why Reha post had wisdom there.
