After some consideration, I decided to just age up one of my fandom OCs, remove her powers since I don't think those exist in this, and use her since I like writing her personality.
Name: Min Sun-mi
Age: Twenty-four
Gender: Female
Sexuality: Pansexual, panromantic
Personality: Sun-mi is a confident and determined person. She is proud of her abilities and strives to use them for good. She is an incredibly hard worker, as well, due to a strong desire to achieve her goals.
She is also a creative person, coming up with solutions and strategies for any situation, even if they are strange. She is sometimes very logical and clever as well.
She's sweet, optimistic, and caring as well. She can put a smile on anyone's face. She worries a lot deep down, but she tries to keep everyone positive.
Sun-mi is also very protective and sometimes impulsive. When she isn't pretending to have optimism for the sake of others in dire situations, she can be very emotional as well.
Appearance: She has a rather pale complexion and stands at 5'6. However, she is a very active person and is lightly muscled. Her typical hairstyle is that of a ponytail, her hair kept up so it doesn't get in the way when she's doing something. While it's naturally black, she will dye her hair from time to time, and it's currently bleached to be white with a fade to a light cyan. Her clothing tends to be on the more athletic and comfortable side, but she'll occasionally wear skirts and such. As for her face, it is round and soft with clear skin.
Backstory: I'm too lazy to rewrite her entire backstory to remove her powers, but in short, she had a pretty happy childhood, is close to her brother, Tae, and she spent most of her childhood with him, and she always admired him for his determination and optimism, which heavily shaped her own. She looked up to him a lot growing up.
Other: I have fun writing her because her personality is unintentionally similar to a character that I like. I didn't even know about the character back when I made her, so it was all a coincidence, but it makes her one of my favorite OCs. Also, her hair was actually a result of her powers in her original canon.
