  • She had a role in CSI: Crime Scene Investigation, in the episode Say Uncle (Season 9, Episode 6). She was credited as Korean Teenager.

  • Olivia revealed in the above video that up until her teenage years she had a distant and awkward relationship with her father, who was often working overseas and never had time to bond with her. However, she also revealed that their first real bonding experience came when she was thirteen, when he spent an afternoon teaching her to ride a bike for her CSI role. Originally, she thought she would hate it, but it ended up being one of her happiest memories to date and a milestone for the relationship between her and her dad[4].
