A documentary-style video set in a "public housing complex" has sparked controversy. This location, a hidden space concealed within an ordinary everyday atmosphere, captures lewd acts disguised as "play" taking place in hallways and landings. The person uploading the footage, referred to as "the uncle," lures curious teenage girls on summer break into a "secret playground," recording everything. Though the girls appear not to fully understand the nature of the acts, they participate as if enjoying themselves. This work presents a shocking depiction of abnormal relationships lurking beneath the surface of daily life.
