Happiness | Park Sunghoon

What happens when the person you never stopped loving is the one standing between life and death?

Park Sunghoon and Kang Nara were inseparable in high school, best friends who knew each other's fears, dreams, and secrets. Until the day Sunghoon disappeared, taking all the answers with him.
Years later, fate traps them under the same roof-a deadly outbreak forcing an entire apartment complex into lockdown. No exits, no safety. And no way to avoid each other.

Now a police officer, who believes he can protect everyone-except the girl he abandoned years ago, and an emergency physician, they're forced to work together to survive-while pretending their history doesn't still hurt.
In a place where trust is fragile and survival is uncertain, can they face the truth they keep running from?
Sometimes, the most dangerous thing in a lockdown isn't the virus-but the feelings you buried.

A Park Sunghoon fanfic.
