Awesome update! All the best with progress and cool news. I looked at the profiles of the characters before answering the questions, they seem really cool.
1. I think maybe Kahlil. He sounds like the type that is uplifting even when facing hell. But it was hard for me to guess as it seems all 3 have lived tough lives.
2. At first I thought Arya as he is world famous but his temper sounds scary. Maybe Guntur as he looks like a bodybuilder but it seems his reputation may have him get seen negatively... this is tough. I guess Kahlil he seem easiest to approach
