Parents often become sensitive to their child’s well-being, Maru was no exception. He started seeing corners of desks as a horrific weapon once he had his daughter. He started putting sponges to cover the corners and went so far as to ban all sharp objects from the house. He used to think his friends were overreacting with their kids, that all kids were supposed to get hurt as part of growing up. But once he had one of his own, he understood. Just watching his daughter cry made his heart drop. He wanted to take care of all sources of danger before she could get hurt.

One day in the past, he was talking with his fellow bus drivers about his cute daughter with a cup of coffee. He got a call from his wife, she told him their house was on fire with a very calm voice. Maru was surprised enough to spit out his coffee, but his wife just hung up casually. He told his boss about what happened and ran straight back home. The door to his house was opened and there was a crowd surrounding his house. The first thing he saw when he ran inside was his wife opening the door to the veranda with their daughter in her arms.

The cause of the fire was a phone...
