The father in the movie is really lucky to have a daughter like Takeuchi, who is not only obedient and gentle but also very understanding of his feelings. Since her mother passed away early, she is very empathic towards what her father is enduring, especially the suppression of his personal physiological needs. It is also for this reason that whenever he comes home from work feeling stressed and tired, she understands and wishes to help him by using her body to provide him with moments of ecstasy and refreshment with his loved ones.
