34 parts Ongoing Chaeyoung had everything: awards, acclaim, the architect's mind that shaped skylines... and the woman she loves.
Until a crash stole ten years of her life.
She wakes up engaged to Mina, the elegant girl from high school she used to bicker with more than talk to - with no memory of how they fell in love. In her mind, she's seventeen again, holding a ring she doesn't remember saying yes to.
As memories return, some sweet and some soul-shattering, Chaeyoung begins to uncover secrets buried under legacy, ambition, and a love that never stopped trying, even when it hurt.
And Mina? She never stopped loving her. She never stopped waiting.
But how long can you wait for someone who may never remember choosing you?
This is the interval between who they were and who they are now.
