[Four? Five? Six Months after July; Presumably sometime in November 2017]

In Hikari's final confession, she questions why couldn't Senpai fall in love with her if he could fall in love with someone as terrible as Okayaki.

Senpai
When she first met Senpai she was intrigued and welcomed him along with the rest of the class. Sometime later her emotions grew and she helped Senpai fit in with the other popular kids. As the days went by she got more and more frustrated when Senpai failed to respond to her advances. During her confessions she attempts to shield her emotions. Even after succeeding with the confession, she continues to find joy in teasing him.

Her affection towards Senpai is questionable. Hikari's diary and Okayaki's dialogue in Episode 023 reveals her affection is only superficial.

Hikari
With her disheveled look and distant gaze, Okayaki deemed her as a crazy person. Thus, she feels entitled to teach Hikari where filth belongs in school. After her resurrection, she decides to get revenge on Hikari because she was killed for something as petty as a boy.

Trivia
Fallenshadow has repeatedly commented she doesn't understand the appeal of a tsundere.
