If by original source you mean the VNs, then judging from the synopsis there probably will be similarities, if not follow the plot to a T.

The OVA compressed all of Volume 1 into an hour, so while it did follow the VNs, a fair bit was cut out. No Milk or her owner for example.

The OVA also cut out H-scenes, and the anime most likely will too. But from the small amount of teasers we have, there will be fanservice.
