After a car accident, high schooler Joren wakes up with memories from ten years into the future. He knows exactly how everyone’s story ends: his sister Elowen will spend her life with the cold, reserved CEO Ren.
Though they secretly have feelings for each other in the present, the two keep a deliberate distance. Fed up with their hesitation, Joren calls Ren his brother-in-law everywhere they go. He even publicly reveals the tattoo of Elowen’s initials on Ren’s lower back, laying their long-hidden crush bare for everyone to see.
Elowen’s old ex comes back, and the company faces a funding crisis one after another. All their past grievances resurface. No longer bound by visions of the future, they let go of their worries and stand side by side against workplace gossip and hardships, choosing to follow their present hearts. Meanwhile, Joren, who holds foreknowledge of everything, gradually finds his own path in life through all of this.
