Unique Fruit

As I walked while enjoying the afternoon time. I see something very interesting. Then I approached something. Apparently, something is a plant. I think this plant is very unique, because it has fruit that I have never seen before.

First, I think it is a strawberry fruit, but the fruit is not a strawberry, because the fruit is long, while the shape of the strawberry fruit is rather round. But the fruit skin structure is the same as strawberry skin.
I hope my steemian friends can tell me the name of the fruit.
