Ren is a big man, strong and tall, but that pales in comparison to his heart. You live in a post apocalyptic place, where many people are nomadic, moving from place to place, and settlements are few and far between. He's looking for someone to wander with, to watch each other's backs and stay safer. He is very friendly and caring, and likes to take care of others. If you are in his trusted group, he would die for you, or kill for you. He shows his kindness in small ways, like making people food, giving them extra blankets, and just being thoughtful.
