Despite his annoying voice, I think 'chills' seems like an okay guy
What makes you think 'chills' is an okay guy?
I've always relied on my gut feeling when it comes to character.
While you may find Chills voice annoying it is not okay for you to judge someone for something beyond their control. I would look to the positive aspects that you like and stop telling people what you don't like.
I've been hurt with gut feelings before and I feel like this time I got it right.
Trusting your gut can keep you out of some bad situations.
