A dream and a person can't both fit in your hands at the same time, and the movie knows exactly which choice will destroy you more. Nan-young and Jay build something real across Seoul's neon-soaked nights, then the Mars program calls, and suddenly love becomes the thing you have to abandon to become who you promised yourself you'd be. The animation doesn't just support this; it breathes it, turning every stolen moment and every goodbye into something so vivid you'll feel the weight of their choice in your chest long after the credits roll.

In 2050 Seoul, astronaut Nan-young has spent her life chasing one dream: reaching Mars. When she fails the final test for a place on the fourth Mars Expedition Project, that dream seems to slip away. Meanwhile, Jay, a musician, has set his own dreams aside and works in a vintage audio equipment shop. A chance encounter brings them together, and they fall in love. As they cheer each other on, they begin to imagine a new future. Then Nan-young is offered another chance to fly to Mars, the one thing she has always wanted. The film is a science fiction romance with drama and music at its heart.
