After entering the university, falling in love will increase the cost of living, because going out to eat and go shopping occasionally will cost more. Like Wu, who spends 5,000 yuan a month in Nanti, his main expenses are eating, shopping and traveling with his girlfriend. "Indeed, after falling in love, consumption has increased, because he and his girlfriend will give each other gifts and so on."

Some students calculated that they would spend 800 yuan more each month after falling in love.

But some people also expressed the view that "cost is like a parabola". Joe is a graduate student majoring in mathematics. He was admitted with his girlfriend this year. He got married and got his license in August this year. He said, "At first, the cost will increase, but after the relationship is stable, the cost will decrease."
