Replying...
Intro. Some places look ordinary from the outside: old buildings, darkened windows, and silent corridors where no one ever goes. But sometimes, silence doesn't mean tranquility; it means there's something hidden waiting to be discovered. When Jenny Chan arrived at this old apartment building on her first night in America, she thought she'd just found a cheap place to stay while she studied. Little did she know that this building concealed more than it appeared. And that the mysterious young man who always stood outside the entrance... would become part of everything that would happen next~~

Beneath the Thirteen Floors~~.
