Explorable Mini-story

"Hello! ;) I have to admit that I read this story because of how short it is since I always read at my workplace. The idea is not new, but I like how you described the change with the phone calls. I think you can explore this story deeper. For example, you can add more detail about the change in the husband's behavior, so that readers can understand her motive of killing him more. I didn't notice any grammar mistake, though. Maybe it;s just because I'm not a native English speaker. Well, hope this helps anyway. Keep up! Regards, Kei Angelus"
