の間に

The expression の間に marks a period of time during which another event occurs or a change happens. It focuses on what happens within that span or while that condition holds. It often conveys that something takes place within a window, sometimes unexpectedly or as a result of being in that time frame. It can also imply that the situation is temporary and bounded by the period described. Typical contexts include describing a change, a chance occurrence, or a contrast between what is happening during that time and what happens outside of it.
