It looks very similar to a Brazilian Cherry Myriam, Eugenia brasiliensis so it could be in the same family.

The tepals remind me so much of Euonymus europaeus, and when I saw the similar looking leaves of one of the fruiting plants, Salacia elliptica, it's in the same family Celastraceae!

I'm leaning towards Myrtaceae, Eugenia does have bracts ..
