Someone she considered a best friend in childhood.
Indie met Rad when she was only a kid traveling the coast often with her family leading to his hometown. She immediately bonded with the younger child and spent as much of the few weeks together they had hanging out whenever possible with him. Hearing they had to leave the region entirely broke her heart because it meant having to leave her friend behind, and she didn't get a say in the matter no matter how hard she fought to stay.
She made a promise to keep sending letters as often as possible and eventually get a flying liscence to make an effort to go back to rekindle their childhood friendship when the letters weren't enough. Eventually letters dwindled out and life started to get in the way, but she would vehemently put aside time to go visit whenever possible. Unfortunately each time was a "barely missed" moment and she never did see him again.
It hasn't stopped her from trying, and she hopes one day that luck will be on her side to reunite with her childhood friend again. She keeps her half of a popsicle charm close to her heart for safe keeping and to warm her heart whenever she feels stressed or down.
She believes they will meet again, wishful thinking or optimism aside and when they do she'll make sure that their missed opportunities become make up memories. She has to! She pinkie promised it years ago.
~ Childhood friend ~
The first person in his life that did not assume bad things about him right away, which made him fond of her from the day one. They spend a lot of time together in the few days they had together before Indie moved away due to her family situation.
Rad started to practice writing just they could stay in contact and as he got older tried to get a flying license but had to give up on this due to his fear of height.
Unbeknown to him, Indie returned to his home down not long after he himself left to go to paldea. They had a lot of "barely missed you" moments ever since, but it seems as though they will finally be meeting again very soon.
He still carries the half of the charm he got from her as a goodbye gift all those years back.
It sometimes makes him very sentimental, as he wonders if they will ever meet again and sometimes it is upsetting that they got to know each other in a time where smartphones were not the big thing yet. Despite that he still feels like they will meet again eventually, just as they had pinky promised all these years ago.
