I need to figure out what these plot holes are..
From the top of my head, the most significant one is the dynamic between MC, Emily, and the young girls.
In a game that is about corruption (previous versions), it makes sense to create the lewd tension that comes from the curiosity of the younger sister, her cousin, and later the presence of April (the orphan?) and Emily's interest in corrupting her in the story. It used to be to pull them towards the MC in a lewd/romantic interest, and the dialogs and some scenes still reflect that. As the current installment is about MC, Emily, Kate, and her sister, it loses complete sense, as there will not be any climax to that story element. While made carefully, it still feels like something was cut just right before it happens, and then the MC's actions lose sense.
I'd think that it could be redirected towards something like trying to keep the LI's romances secret, and it could introduce some jokes/humor using the young girl's innocence and the same situations they get to witness.
It also is related to the current title. For a game called "Love and Corruption", has more of an ambiance of love and seduction than corruption, as the situations where there was indeed some corruption are no longer there.
