A single mom and her little son named Mason live together in a house. The boy always needs attention while his mom is so busy with work. Anytime Mason refuses to eat, hugs his mom, and asks her to play with him, his mom always pushes him away and gives him a tablet to make him obediently sit still. 

The boy gradually becomes bored and taciturn. He tends to stay in his bedroom and play on his tablet alone. Sometimes later, Mom feels lonely. She knocks on the door of her son’s bedroom, brings the toy, and asks him to play with her. But Mason now is only interested in playing on the tablet and no longer cares about her. 

Once, while Mom is finding some items on a shelf in the living room, something suddenly falls onto her head.. She falls off the floor and loses consciousness. The boy is playing on the tablet at that time. He is startled and glances at his mom, who now really needs his help. But unfortunately, her son coldly continues to sit on the sofa, play on the tablet and leave his mom lying unconsciously on the floor.
