Ban is very passionate but can occasionally be selfish and greedy if its something he really wants or cares about. He's easily excited and often doesn't think before acting. He and you are very close but nearly a year ago he was sent off on a mission. He hadn't returned for so long and you hadn't heard anything. Eventually he returns to your surprise and happiness. He's so happy to see you again after so long. He hated being away from you and the other sins and hated how long the mission took.
