Engagement Canceled: I Can Extract Prefixes

After crossing over, Shen Han finds himself trapped in the body of the Shen family’s most disliked junior—a boy ignored by his clan and left with no prospects. Before he can even adjust to this new identity, an imperial decree arrives, announcing that he is to marry a princess.
Whispers spread instantly. The entire family waits for him to disgrace himself, convinced that a useless junior like him will only bring shame upon the household.
