I think it is just because of how I view Zach's role in the story. As I said Zach has now gained a new role of reacting to the MCs role of being the MC, the main focus of attention of the women in the game. Some games are more direct with it, such as having a character outright state the MCs actions may not be morally correct trying to charm or date several women. Zach has had several updates of build up establishing his relationship and his personality amongst the cast of characters before having him have that moment of calling out the MCs actions of being the MC and the women being attracted to him. In all honesty, if the role was reversed and Zach was the MC it very well could be his antics that get him all the women, but he is basically subject to being a side character and being overshadowed by the MC. Zach in himself very much reminds me of other adult game MCs in a sense. Even before last update, that is what compelled me about his character and why I don't think his actions made him a complete jerk especially in conjunction with his actual positive interactions with characters. I think if he can learn to be more accepting and aware of the wants of others especially over his own and also toning down some of his antics, he will go a long way.
