When reading a novel, the heartache could be due to too much emotional investment or the story being too touching. When we read a novel, we are often attracted by the plot and emotions in the novel and put ourselves in the world of the novel. This may cause our emotions to resonate and even invest more emotions. When we put too much emotion into it, we may feel heartache. This is because emotions and consciousness are independent of each other. When we put in a lot of emotions, our consciousness may be distracted and unable to fully perceive our emotions. This may cause us to feel heartache as if we are feeling pain in our bodies. When we read a novel, our hearts hurt because we feel sad or lost because we resonate with the plot of the novel. In this case, the heartache may be because we feel similar to the characters in the novel, experiencing similar emotions and experiences. The heartache when reading a novel may be due to too much emotional involvement in the story or the distraction of our consciousness.
