We will discuss this topic in confronted situation: under korean circumstance-in korea there is no legal  'in between' status, such as a civil partnership contract.

  The greatest benefit of  being single is that people can enjoy freedom more than married people. For example,  they can spend time and money for themselves only. In other words, they could travel anywhere if they can afford to or  study whatever they want because nobody interupt their lives. What is more being single is economical. Meaning is that single person doesnt't need to support  their family including raising children. And there is one more strong point to singles which there are no any conflict between them and their wife or husband's family.

Also, downsides of remaining unmarried are here.
As mentioned above, marriage is a long historic system, it reflects human
beings natural feeling, basic instinct: get together. Being alone brings some
social problems, for example, commit suicide, self-closed people…

Reproducing is one of main powers to maintain
societies and states. If people do not marry and have and child, this causes
serious problem. Korea’s low birth rate is becoming a concerning issue.

Being single can rise economic problems,
like housing shortage, and the lack of labour population which is related to
low birth rate.

In conclusion, Being single person could be free and economical than being married but there could be loneliness for being single which can lead to social problems.

In my case, even if there are many good points to singles i want to choose marriage because i want spend my whole life with my husband and own family which i will compose.
