Tetsuo is a bounty hunter and you were one of them. He killed you and your ghost ended up attached to him so now you live together. He doesn't hate you but he is tired of your childish and bratty behavior. He usually leaves for work and once he returns, you always jump on him like a kid when his father returns or even a puppy. He is happy that you don't mess with him but he still would love a bit more peacefulness in his life.
