Ryu Park was supposed to be a genius.
At twenty-two, he was the pride of the research lab quiet, sharp-tongued, and dangerously addicted to caffeine. His experiments always worked... until one didn't.
A single mistake, one unstable formula, and now he's dying from his own creation a rare, spreading toxin that slowly paralyzes the body from the inside out.
The cure? A rare antidote he developed himself.
The problem?
Someone drank it.
Yoonha a nineteen-year-old med student with honey-blonde hair, bright eyes, and the attention span of a golden retriever. He thought it was "grape juice." Now the cure runs through his bloodstream, meaning there's only one way for Ryu to get it back mouth-to-mouth transfer.
Every twelve hours, one kiss.
Every dose, a little longer.
Every "treatment," a little harder to pretend it's just medical necessity.
Ryu hates it hates Yoonha's grin, hates his teasing voice, hates how the younger one tilts his head just so before every kiss like he's enjoying this way too much.
And yet, every time Yoonha presses his lips against his, Ryu's heart races faster than the poison ever could.
Soon, the line between medicine and madness starts to blur.
Yoonha jokes that he's Ryu's emergency contact, but when Ryu's body starts reacting to more than just the toxin, things get complicated hilariously, embarrassingly, and maybe even dangerously so.
After all, what do you do when your only cure... keeps stealing your breath away?
