Give the protagonist a task, not just an enemy
A wrong done in the opening can make the audience choose a side quickly. The next episodes need an objective that can be advanced on screen: find the forged record, win a bout, identify the person behind a sabotage, or recover a stolen design. Each task gives the viewer evidence of progress.
The opponent should be able to respond. If every plan succeeds immediately, escalation becomes a list of punishments. If each discovery changes what the enemy can do, the comeback gains momentum without repeating the same confrontation.
Change what victory means
At the start, the goal may be public vindication. By the middle, the protagonist may learn that exposing the truth could hurt a sibling, colleague, or customer. That cost complicates the revenge without taking away the original wrong.
This is especially useful in an 80-episode format. A sequence can move from discovering the method, to finding proof, to deciding whom to trust, to choosing how to use the proof. The story is still focused, but each phase asks a different question.
Make the payoff visible and specific
A confession or a public speech may resolve a plot, but a more memorable payoff often returns to the object that caused the damage: the forged entry, the disputed garment, or the rigged fight. It lets the audience see that the protagonist has changed the terms of the conflict.
When assessing production scope, look for recurring locations that can serve new purposes as power shifts. A restaurant, gym, office, or atelier can support many episodes if each visit changes who holds evidence or authority.
