JisungHannies
In the shimmering coastal city of Aethelgard, thirty-year-old cardiologist Lee Minho is a master of precision. Known as the "Zero Degree," he is the hospital's iron pillar-a man who navigates the line between life and death without ever shedding a tear.
But even pillars crack. Six months ago, Minho's world fractured in private when he and Seungmin, an ER medic, ended their long-term relationship. Though they remain part of a tight-knit friend group led by the protective Bang Chan and his wife Alexis, the breakup left a hollow space in Minho's chest that no medical logic can fill.
Now, a suffocating mental dread has begun to drown him. His best friends Changbin, Hyunjin, Felix, and I.N watch in terror as their "invincible" hero slowly turns to stone.
Everything changes during a midnight walk when Minho meets Jisung, an eccentric child therapist who talks to stray cats and hands out gold star stickers for "surviving the day." In a city of high-stakes and heartbreaks, Minho is about to learn that sometimes, you have to break completely before you can truly be mended.
