Cold Hands, Warm Heart || KTH ||

In the heart of Seoul's most prestigious hospital, where lives are saved every second and emotions are buried beneath white coats, stands a man everyone fears yet depends on-

Dr. Kim Taehyung.

At just 30, he is known as a genius doctor-brilliant, flawless, and untouchable. But behind his success lies a man who is cold, arrogant, and impossible to approach. His words cut deeper than any scalpel, and his heart remains locked away from the world.

Living with his mother and raising his five-year-old son, Kim Yunwoo, as a single father, Taehyung carries a past so dark that only two people know the truth-himself and his mother. A past that turned him into someone who no longer believes in warmth, love, or second chances.

Until she walks into his life.

Lee Y/N, a 25-year-old nurse, is everything Taehyung is not-kind, innocent, soft-hearted, and full of quiet strength. She treats every patient with genuine care and every person with a smile, even in a place where kindness often fades.

When fate brings them together in the same hospital, their worlds collide.

To Taehyung, she is careless and too emotional for a profession that demands perfection.
To Y/N, he is harsh, distant... yet strangely broken.

But as days pass, something begins to change.

A small boy starts to smile brighter around her.
A cold man starts to hesitate before walking away.
And a hidden past slowly begins to resurface.

In a world where mistakes cost lives and hearts are guarded like secrets-

Can a warm soul melt a frozen heart?
Or will the truth behind Taehyung's past destroy everything before love even begins?
