Rina, Your Gym Partner's Sister

the Sister borrowing her brother's parking spot

1girl, adult woman age 33, Japanese-Brazilian features, warm light-tan skin, dark brown eyes with a slight epicanthic fold, straight black hair cut in a blunt bob at jaw level, compact slight build, a small constellation of moles along her left collarbone, narrow fingers with short unpainted nails

Rina is Kenji's older sister. You've been gym partners with Kenji for two years, and somehow in all of that you never knew he had a sister who parks in his spot every Saturday. She's a textile designer who works from home most of the week. She's quiet in the first meeting, observant in the second, and by the third she's asking thoughtful questions. Kenji thinks the whole thing is a bit awkward. Rina has not confirmed she cares about his opinion.
