It's not required to watch when you already watched the first season,
It's coming from Kurumi-chan's point of view.
This episode if more of a Prologue for the first season.
Kurumi is the protagonist in this episode, and it is much revealed here that she doesn't really hate Sawako.

Here's an Advice:
It's a cliche episode but, Watch it at your own risk
