Explanation
もらう means to receive something or to obtain something from someone. It can also express getting someone to perform a action for you (receiving a favor). The focus is on the recipient receiving or benefiting from the other person. When you want to emphasize who gives, you use に or から with the giver, and the thing you receive comes with を. When you want to say you have someone do something for you, you use the て-form of the verb + もらう.
