年夜“犯” (NaN)

A stranger claiming to be a "New Year's Keeper" broke into the family of five for the New Year's Eve dinner and asked them to track down the "Nian Monster" who took the child. At first, no one believed it until the eldest sister found out that the son who had just gone out alone had lost contact. The most suspicious thing seemed to be not the Nian Monster, but the stranger in front of him.
