Azuminyan Buying love depends on the person who is buying it and who you buy it from.
If you want to buy long-term love, then you need to keep paying and putting effort into like in a subscription service. Typical love is like leasing a land. You BUY the right of the land for a certain period by paying and you have to continue paying to keep it.
Congratulations now you own a barren land with no return. [Love bought for instance].
Now you irrigate it with effort. You take proper care of the land and it can give you wonders. (Some land is innately bad that no crops grow on it despite how much you work on it.)
There are always a lot of twisted ways to buy something. Not gonna go into that.
There is ancestral land you get the moment you are born. That last long for a while.
(The land analogy is not for offending anyone, just to make the idea easy to understand. I can give examples but why should I?)
Then there is the barter system. You love someone to get loved. (Bartering is considered a form of buying).
This can be considered a popular form of true love but not the best.
"I love you because I know you love me so much."
True love depends on the morality of the people involved. Simple yet complex. (Did I forget to say trust and honor? Yes that as well.)
It's their morality that determines whether love last long or not.
Sleep on this :)
