Mi Sun was born to a humble couple in South Korea and was the second child and only daughter. From birth Mi Sun was a happy little bundle of joy and her family adored her, even the local residents in their neighborhood thought that Mi Sun was just the perfect little baby.
Growing up Mi Sun was usually always happy and bubbly, she loved to explore and learn new things and didn't like conflict or bad emotions. She tried her best to avoid them, which led to her being very sensitive whenever someone raised their voice or got upset at her. As a child, she would cry at any negative emotion, which made it difficult to parent her.
It took her parents some time to teach their daughter, but eventually, she was able to control her little meltdowns. It wasn't until her little brother came along that she was fully able to handle her emotions, as whenever the baby cried she would cry since she thought that she had done something to him. Little by little and with much practice, she overcame it.
When her oldest brother went off Mahoutokoro, Mi Sun wanted to go with him but her parents explained that she couldn't go. She was pretty upset at this and ended up showing her first signs of magic at 9. She broke out into a fit, crying and trying to convince her parents to let her go. When they wouldn't, she ended up breaking a vase that was in their living room. Their parents were surprised, but also a little glad since it meant their daughter wasn't a squib.
A few years passed and Mi Sun went off to Mahoutokoro as well, joining her brother and just over excited to learn. It seemed like her years flew by as she went to school and returned to home to help work at their family's tailor shop. When Mi Sun got the invitation to be an exchange student at Hogwarts, she immediately jumped on board. Although it took a little bit to convince her parents to let her go, eventually they agreed and signed the paperwork to allow her to travel for the program.
Mi Sun doesn't know what Hogwarts has in store for her, but she's very excited for the experiences that are coming and hopes to meet a lot of people and learn more about England. She just hopes she doesn't get lost, or mixed in with the wrong crowd of kids.
