You know, I'm just gonna put this out there. Rereading and rewatching rent a girlfriend, I've realized something. I actually like Mami Nanami.
And before you attack, let me present this to you. She was in a toxic relationship technically. Kazuya always made her uncomfortable because, and we all know it. He just wanted to get his pole greased. No one should ever be in a relationship where they don't feel safe or uncomfortable.
So, yes. Mami is definitely manipulative. But Kazuya deserved to get dumped by her.
Also, in regards to my stories, I'm working on the Rent a Girlfriend story.
