In India, the first priority for a healthy and wealthy life is stability and a job. But, unemployment is so high that the counting of the youth is now beyond 18 to 25 years of age. It ascends to 30 to 35 years. And because of these conditions, the youth is not ready to take much responsibility for love and start a family on their own. Casteism is one such factor too.
People know their boundaries and some, not all follow casteist rules. They have no freedom to choose their partners by themselves. So they just do time pass and hookups in the name of love.
