The Neighborly Big Sister!

The apartment complex where Lin Baici lived was over forty years old, and the soundproofing had never been any good. Even the sound of kids running around was enough to drive you crazy, let alone loud, trashy music. With all that noise late at night, there was no way anyone downstairs could sleep.
