Review Detail of Grand_Go in Strongest Mage with the Lust system

This story has really good potential but I don't like the inconsistency in the character design of the mc. Later in the story it comes to the light that system was made by another mage which tries to control him which is really bad but it's okay. But what annoys me the most is that that man takes control of the system and watches everything through system while mc is having se* and advices mc to do 'this or that' while mc is having sex. It is really disgusting. MC is inconsistent about how to deal with women, there is no romance only se*.
