Ren
Renata "Ren" Ghali
The main character of Planetfall, an engineer.
- Amicable Exes: Kay broke up with Ren because of Ren's refusal to open up, but they're still friendly (and still flirty).
- Companion Cube: In her hoarding, Ren anthropomorphizes her things. She sees herself as adopting them, loving them when no one else will.
- Daddy's Girl: Ren and her father were very close, while she and her mother were not. Even when she's nearly 70, Ren still recalls her father frequently and fondly.
- Love Father, Love Son: Ren was in love with Suh, and is attracted to her grandson, Sung-Soo, because he strongly resembles her. Ren finds her own attraction uncomfortable and inappropriate.
- Mother Nature, Father Science: Ren's mother—an artist—was not supportive of her work, on the basis that it was too much science, too artificial. Her father, on the other hand, was very proud of her.
- Outliving One's Offspring: Ren's daughter, who died at age 3.
- Socially Awkward Hero: Ren—like the author—suffers from anxiety.
- Trash of the Titans: This turns into compulsive hoarding.
