「〜次第（しだい）」- As Soon As

Explanation

〜次第 is used to indicate that once the first action is completed or realized, the second action will immediately follow. The first part usually describes a natural progression or actual situation, while the second part is an intentional and proactive action. Since the second action is something that will happen in the future, it cannot be in the past tense.
