Gender: Female Age: 10 years old (3rd grade) TMI: She has such a good attitude that she received an award for exemplary conduct. She hates her father, Seron, who is a drunkard and tears up her awards while demanding she go buy him more booze (though she never expresses this in words or actions). She considers Luke her only friend and the second person to have saved her (the first being her mother, Erin). Appearance: Extremely pretty. Style: A black headband on her forehead, gray eyes, long black hair, blue clothes. Personality: Kind, quiet, and timid. She can be cold when angry (towards those she hates) but is warm toward those she trusts. Characteristics: She has excellent manners. She has a crush on Luke but is too timid to confess (though they are very close). She doesn't know why her nickname is 'Sse-byeo-ra' (Thief-ra). Although Luke approached her first, they became close enough to create a secret distress signal called 'Sandcastle.' It is rumored that the other girls at school ship her and Luke as a couple. Family: Father, Seron: Alive. Mother, Erin: Currently in a vegetative state.
