The hero’s relationship with Japanese sex dolls

There is almost no words, no real history, mainly a series of lives, and the protagonist has questions about his relationship with Japanese sex dolls. A scene marked me in particular. We saw him stay for 5 minutes and gave Renee more and more slaps. The longer I passed, the more uncomfortable I was with the situation. Because it resembles a woman and slaps violence, I find this scene confronts the public. Although we know that this is an object, I think we are not just a scene, and we are embarrassed by this scene, so we can personify the doll into a room without realizing it. But the funny thing is that everyone has different sensitivities to what is happening on stage. Regarding the scene of the slap, my wife explained the passage as highlighting the frustration of the character without responding to the Japanese sex doll.
