The structure of the leaves do not match the pictures on the links provided by … Nor does the structure of the branches.
The branches in the links attached by …, are a bit hairy and the leaves are dull and not glossy like those in the pictures sent

I guess it can be some Boerrhavia species. the flowers looks very much similar to Boerrhavia except the color.

---

any chance of getting fruits photo? so that the id can be confirmed.

It seems to be Pisonia rotundata.

Yes, to me it looks like Pisonea aculeata only, the leaf is slightly different from the specimen I collected
