It's a great character analysis, what I find incredible is that normally in games like this the secondary characters have almost no focus, so you can tell that the dev took care of the game. What I love about Gleen's character is that he is a humble character, there is a really cool scene in the game, if you choose to follow Emma's path, the MC meets with Gleen and instead of him getting angry at you for abandoning his daughter, he wishes you luck, of course he's sad that you left his daughter but he understands that it's your choice and he doesn't judge you for it.I love Glenn's character because he is exactly the example of the father I want to be. A humble man, who teaches you to have values and to always follow the right path. I think his relationship with Gwen is really cute, the way they are alike, the way he supports his daughter's dreams, if one day I have a daughter, I want to be exactly like that when I become a father.
And thank God NiiChan didn't make us have sex with Gwen's mom, because I would have felt really bad for Glenn, because if this game was written by someone else, definitely would have done that.
