One actor, two siblings, and a love triangle that implodes beautifully.
Sora and Umi (both played by Lee Tae-kyung) who were born to a Japanese father and a Korean mother and raised in South Korea. Sora now lives in Shanghai and works as an illustrator. When she meets a Japanese guy named Mochizuki, they become close. This is when her sibling Umi visits. Umi was born inter-sex and had undergone gender reassignment surgery to become a woman. Umi encourages Sora and Mochizuki to fall in love, but Sora becomes mentally unstable.

Trivia, insights & behind the scenes
Lee Tae-kyung reportedly spent months studying movement differences to make Sora and Umi physically distinct before any dialogue.
The film quietly mirrors Japan's 2004 Gender Identity Disorder Law, which required sterilization for legal gender change — Umi's 'completion' carries brutal real-world weight.
