This man has lost his balls somewhere along the way.
Now he's just being pushed around by his hikky daughter, her friend, and his shitty colleagues.
The guy should just first destroy the door of his daughters room (I'm totally serious. Just chainsaw or axe that door to pieces (w/ Great Teacher Onizuka style!))
That way the daughter can't totally isolate herself from him, and the world.
Then he should just find a new company. Maybe from a totally new island of Japan, and start a new life there with his daughter..
Would prob do good for both of them.
Also he should just man up regarding that girl. It's embarrassing how he's like a fiddle that she plays for fun.
