Lee Shuang

Shuang is Lee's cousin who cannot walk due to a genetic defect. Being in a wheelchair, she seems to be heavily guarded by the Lee family, and is strictly forbidden to go into the "outside" world.

Due to these circumstances, Shuang grew up to be a naive and highly idealistic individual who barely knows anything about the world outside of her home, and believes that there exists the possibility of making everyone happy.

Shuang is generally mature and calm, and enjoys teasing her cousin a lot, especially about his relationship with Lucia.
