It's never even crossed my mind before but I just realized that my OC's Seafoam and Cherry Chirp have a lot in common. It took me till I was looking at my OC dragons on Flight Rising to realize, "Wow, they have really similar colors" and that sparked a huge train of thought.
Seafoam lives in either Chinatown or Japan, haven't fully decided which I want it to be yet, and she loves Asian culture and food. She works at a seafood market, which is related to her cutie mark.
Cherry Chirp has his cutie mark in cranberry farming, which isn't all that similar, but i'll tie that in in a second. He's somewhat of an anime nerd, and loves traveling the world and seeing what there is to see.
I had already decided that Seafoam wasn't born where she is now, but she lived on the coast as a young filly which is how she found her interest. Pehaps, going off the idea that they could be siblings, maybe the two of them loved swimming from a young age, which is why Chirp's cutie mark also has to do with water? Then they moved, where they lived for awhile until Seafoam moved out, being a bit older than her brother. This would be about when Chirp found his cutie mark. Having a sister working in an Asian market and surrounded by the culture could have led to Chirp's interest in anime, and sparked his interest for traveling. I'm sure Seafoam got visits quite often.
This...is gonna be official, ya. I like the idea more after writing it out, so...take some official backstory.
