Not For Sale || λ°μ±ν (Park Sunghoon)
32 parts Complete Sunghoon looked at her, eyes soft. "This time, it's not a package from your mom or some random store. It's just from me. To you. No tracking number, no return address. Something that is Not For Sale"
Harin never cared much for romance until the letters started arriving. Sweet, heartfelt confessions from a secret admirer who seemed to know her better than anyone.
And somehow, every time a new letter appeared, Park Sunghoon, her annoyingly charming, ever-mysterious delivery guy was always nearby.
Coincidence? She didn't think so.
But when Sunghoon suddenly returns to school after a mysterious suspension, bringing along rumors, secrets, and a past he refuses to talk about, Harin realizes the real mystery isn't just about the letters.
