I agree with you in many ways. Tate doesn't know how to behave with people, but it's not his fault. I think the bigger problem is the one-sidedness of the plot. What I mean is: you are literally told almost at the very beginning of your journey to choose the path of the character. And that's it, you chose it and you no longer have the opportunity to go to another route, only to a bad/ neutral / good ending, no more. I hope that there will be more choices in chapter 2.
