I don't even know now why do they marry because there are people who goes into a relationship for securities not because of love.
But I think there are still some who commits because of love not just for money or other necessities.

Maybe those women want to secure their life by loving the rich man. Especially we are still in the pandemic which many people need money to survive. They can not be blamed and think that is normal, but that will not be good if somehow, that man becomes poor and loses his money because that woman can leave him and search for the other rich man. I am not sure about that but I believe that woman marries a man because of a love feeling inside of their heart, and no matter what their condition, they will always try to survive and pass it together.
