Backstory
Rie grew up in a simple but sweet family that made sure she always retained her bright outlook on life. Even if harsh things came her way, even if she tripped and fell or hurt herself, she'd smile through it because she was mostly okay. She never really had anything serious occur where she knew she couldn't smile through, and had a decent upbringing with a number of family and friends around mutually supporting her. However, when she did finish middle school, her father had a work injury bad enough that he wasn't going to be able to work properly in the future.
She tried to lift his spirits by simply staying as she was, smiling, but that might've been the most stressed she'd ever been. She didn't show it to her family, but her friends at least knew of the circumstances. Her best friend Giacomo, a couple years older than her, said if she ever wanted to work in his family's postal business, they'd welcome her with open arms anytime. Financially, she was fine, but she still wanted to be prepared for the future in case anything ever happened to her mother or father moving forward. Determined, she started working around the age of 16.
When she started, she learned to sort mail and figure out what goes where. She was eager to learn, knowing that if she stumbled she'd get it eventually, and she certainly did. As she got older like Giacomo, she accompanied him as he delivered mail to their town. It never felt like work to her if she spent most of the time talking to a friend, someone like a brother to her, so each work day went by quickly.
Her work even allowed her to meet new faces and become acquainted with those around their town. Older people especially warmed up to her, finding her energy pretty refreshing. As for people closer to her age, she did get along decently with them, even asking some of her friend from school to join her at work during the summer. Galene took up the offer, but she did more of the sorting and indoor tasks than going out and getting lost in neighborhoods she didn't know. Rie was so used to it by now that she knew exactly what the homes looked like without reading the numbers, even recognizing some of the inhabitants.
Acclimated to her work, Rie prefers to work year round, unphased by weather conditions in the winter as well. She doesn't think it'll be the work she sticks to as an adult, still intending to attend college and do greater things in the future, preferably something where she gets the time to do some traveling. Giacomo is the same, a lifelong inhabitant of their town that wants to see what else is under the same sky, so there's been countless conversations to take trips in the future together at the very least.
