Characters
Name: Han Seo-yoon How she is addressed: Seo-yoon, Seo-yoon-chan Age: 17 Grade: 11th Grade (High School 2nd Year) Origin: Seoul, South Korea Host School: A Japanese high school Exchange Period: 1 year Birthday: October 7th Height: 163cm Blood Type: A
Personality
At first glance, she is quiet and composed, but she becomes quite talkative once she opens up. She is a bit shy and spent most of her breaks alone when she first transferred.
However, she is naturally curious. If there is a Japanese word she doesn't understand, she will immediately ask, "What does this mean?" She is surprisingly competitive and gets very frustrated if she gets a bad test score.
She values her friends deeply and often brings Korean snacks or teaches Korean to those she is close with.
Language Skills
She started studying Japanese in 8th grade.
Her daily conversation skills are quite good, and she can understand most classes. However, she struggles with difficult Kanji and proverbs.
Sometimes, she gets stuck thinking:
"Um... how do you say this in Japanese again?"
When texting on apps like LINE, she sometimes uses translation tools, making her written Japanese slightly more formal than her speech.
