Welcome to Our Home(2015)

Welcome to Our Home is a Japanese drama series following Kenta Kurata, a timid commercial designer living with his parents and younger sister in a suburban home. When Kenta unexpectedly confronts a man harassing a woman at a train station, his uncharacteristic act of courage sets off a chain of unsettling events. Someone begins targeting the family's property—destroying garden flowers and vandalizing their bicycle—while Kenta's sister Nana is simultaneously stalked by her ex-boyfriend. As strange incidents escalate, the family must uncover who is behind the harassment and what motivated the attacks. Based on Jun Ikeido's novel "Yokoso Wagaya e," the series blends domestic tension with psychological suspense as ordinary life becomes increasingly threatening.
