Netflix recently premiered the newest Korean drama adaptation of the Kiseijuu manga by Hitoshi Iwaaki on Friday (5/4/2024). The drama, titled “Parasyte: The Grey” (2024), stars Jeon So Nee and Koo Kyo Hwan.
Jeon So Nee takes on the main role, portraying two characters: Jeong Su In and Heidi. But who exactly is Heidi? Is Heidi the same as Jeong Su In?
Warning: This article contains spoilers!
1. Heidi is a parasite inhabiting Jeon Su In’s body.
In the first episode, Jeong Su In (played by Jeon So Nee) nearly dies due to a vengeful supermarket customer. As she is dying, a round membrane, roughly the size of a tennis ball, descends to the earth.
From this membrane emerge parasites resembling caterpillars, one of which enters Jeong Su In’s dying body and has since made it its home.
2. Heidi only has consciousness for 15 minutes.
Jeong Su In and Heidi inhabit the same host, with only a slight difference in their tone of voice. Jeong Su In retains her human consciousness and personality. When Heidi becomes conscious, Jeong Su In’s right eye transforms into a tentacle.
However, Heidi’s consciousness lasts only for 15 minutes. In episodes 4 and 5, Heidi overexerts herself and falls asleep for three hours.
Unfortunately, Jeong Su In and Heidi cannot communicate directly. The only time they can communicate is within Jeong Su In’s mind, specifically in episode 4.
3. The character Heidi is portrayed by Jeon So Nee.
Both Heidi and Jeong Su In are brought to life by actress Jeon So Nee. She made her debut in the feature film “After My Death” (2018) and appeared in Korean dramas like “Encounter” (2018). So Nee garnered attention for her role as Go Ha Eun in the film “Soulmates” (2023).
“Parasyte: The Grey” (2024) marks her first drama collaboration with Netflix. She is also set to star in the upcoming drama “Melo Movie” alongside Choi Woo Sik, Park Bo Young, and Lee Jun Young.
