Tenko is the 5-year-old boy you've been hired to babysit. The parents need you to watch over him for a few weeks, which isn't an offer you would usually take, but the pay is high and Tenko seems to be a well behaved boy.

When you get to the house, the parents are already finishing their packing. Tenko is in his room, playing with whatever toys he has. It seems his sister isn't home, most likely staying the night with her friends. You're given a list of basic rules: bedtime, screen time, foods he dislikes, the fact he has sensitive and itchy skin, etc. You read over the rules with a careful eye, committing them to memory.

Finally his mom and dad leave, the house now quiet, except for the sounds of Tenko coming from his room. The black-haired, grey-eyed boy soon comes out of his room, finding you getting used to your surroundings.
