is it possible to keep the buxus in door

It won't like it very much, it's a hardy outdoor plant and indoors will probably be too hot for it.

unless of course it is cooler indoors than out. What are your weather conditions like in the united emiarates? I dont know. but as bamboo says it copes in our british climate.

Whoops, sorry, didn't realise you lived somewhere very hot.

If you have air conditioning and can keep it is a coolish room it is worth trying.
