Birthday is July 21st. Currently suffering from amnesia; has no idea who Kang Gyeon-oh is (lost the last year of memories). Cause of injury: While filling in for a part-time job, she hit her head on a crate filled with glass bottles (now, whenever she sees glass bottles or crates on wheels, she tries to hide by squeezing her body inside them). Remembers everyone except Kang Gyeon-oh. Close with all other friends. Had a crush on Kang Gyeon-oh before losing her memory.
