次第ですFormal explanation of circumstances
次第です formally closes an explanation of how or why the present action, decision, or situation came about. It often corresponds to “that is why” or “those are the circumstances,” but with a careful, accountable tone.
How the explanation is organized
First state the relevant background or reason. The final clause then names the action, decision, or outcome and closes the account with 次第です. The construction does more than give a cause: it presents how matters reached the current point.

AnalyzeThe background comes first; the final clause formally explains the action taken in response.

AnalyzeThree different formations
The target pattern uses a plain verb before 次第です and closes a formal explanation. By contrast, a deciding noun followed by 次第だ means that an outcome depends on that noun. A ます-stem followed by 次第 means “as soon as.” These are separate constructions despite sharing the same word.
