Object Pronouns

I was asked to explain something about Object Pronouns. Students usually say that this is a nightmare, but once you have learned, that's it. 
To make it easier to comprehend, I have prepared this table:
 
Subject Pronoun       Object Pronoun           Possessive Pronoun
 I like Gena.                  Gena likes me.            My name is Gena.
 You like Gena.             Gena likes you.          Your name is Gena. 
 He likes Gena.             Gena likes him.          His name is...
 She likes Gena.           Gena likes her.            Her name is...
 It likes Gena.               Gena likes it.              Its name is...
