It's hard for me to describe how I feel about some of the characters. Some of them I don't have much of an impression of at this point, but I do know that from what I've played, Caijoru is a mixed bag.

This does contain spoilers so:

Rationally, I understand how he must feel, but it's like he's at a point where he's so messed up that he has trouble even considering that his plan is a horrible thing to do to someone else. He knew what would happen if he took Jeffrey / Colin to the cave. But he wanted to go and wait however long it took to try and get his brother to let him return. It's difficult when you give someone a chance, especially after having someone abuse you in a relationship to then turn around and have the trust you're trying to put in them betrayed. 

As much as I wanted to hate Jeffrey at first for being really childish to people who cared about him, the more time went on, the more I understood it was more reaction than just lashing out for no reason. Honestly, I understand it pretty well, having stress in your life to the point where small things feel so much heavier than they should.

Ted, I mean, if it's true that Caijoru can eventually be pushed to the brink and see that he should move on, be the person he wants to be, I'd want to hope he could live a good life, that any of the bad things inflicted on him or by him, that those could fade away with better decisions, honesty, and embracing people rather than trying to use them.

I'm not entirely sure if the ending of the route where Caijoru comes back to be Ted one last time with Colin as the curse is taking hold is meant to be read the way I saw it, but it felt really sad. The thought of not seeing exactly what happened, my mind immediately thought of the journey Colin had been on throughout the story, where he didn't want to feel like he was going to keep failing everyone around him. So, instead of becoming what he feared, he shot himself after telling Ted he loved him, preventing the curse from moving on. What happens to Ted in that case, I don't know. But I don't know which would be worse: Colin shoots himself, or he shoots Ted and then himself...

I was surprised with Sean. There were some moments where I suddenly felt like he was who Colin should have realised sooner was truly special. And Daren, I don't know what to say. He's such a good person, I just want the best for him always. I think I'll read some more paths when I feel less overwhelmed by the sadness.

The writing between Jeffrey and Daren is so strong in this route, and the last dream with Caijoru was fantastic.

So much happens with Ted and Jeffrey's characters towards the end that I feel that the game ends a bit too soon. After such an intense climax, you could take your time showing how the characters' new lives settle out.

I think this is the strongest ending so far, and FbI's writing is getting better and more refined with every update.
