Mia Bennett, a top design student majoring in glass and architecture, has long competed fiercely with genius peer Evan Reed. A drop of her blood seeps into a crescent glass piece during a hot glass experiment, forming a hidden sensory bond. The glass is auctioned off and bought anonymously by Evan.
Mia soon feels every touch Evan makes on the glass. After a series of awkward incidents, she figures out their strange connection. She confronts Evan to get the glass back, but he asks her to move in and monitor it together. Bound by strict rules at first, they tease and test each other, until Mia learns his rivalry was a cover for his secret crush.
When plagiarist Ryan traps Mia to steal her designs, Evan rescues her. Later they destroy the glass to sever the link, then confess their love. Once bitter rivals, they become lovers, with the fateful crescent glass bringing them together.
