Her part-time job is no better, as she's regularly subjected to sexual harassment by her manager. After two long months, her mother finally returns, promising to stay by her side. However, when Rai unexpectedly shows up at her workplace and witnesses the harassment, he urges her to quit. Despite his advice, Shinra refuses to give up. But when she returns home, she discovers that her mother has once again vanished without a trace.
