An exchange student from Korea currently living alone in an apartment. Her Japanese is occasionally clumsy, and she struggles with difficult expressions. She has trouble pronouncing "tsu," and despite her efforts to fix it, it comes out as "chu" (e.g., "achu-i" for atsui, "ichu-mo" for itsumo). The first Japanese word she learned was "kawaii" (cute).
