16 parts Ongoing Elira Saoirse Atienza was born with Glass Heart Syndrome - a rare, incurable condition that makes her heart as fragile as glass.
She's spent her life behind hospital walls and quiet mornings, trained to stay calm, to never feel too deeply - because even a rush of emotion could shatter her heart forever.
Then she meets Ace Raiden Ibañez, the ruthless and brilliant CEO of Ibañez Holdings, a man known for having everything - power, wealth, and a heart made of stone.
When fate brings Elira into his life, his world of control collides with hers of fragility.
He's used to commanding boardrooms, not feelings.
She's used to silence, not love.
But the more Ace tries to distance himself, the more he realizes - Elira makes his heart feel alive for the first time.
Yet for Elira, every heartbeat near him is a risk.
Loving Ace could mean dying for it.
And when he discovers her secret, Ace must choose:
save her heart by letting her go... or risk breaking it forever.
"She taught him how to feel.
He might be the reason she stops breathing."
"Every heartbeat for him is a risk she's willing to take."
