Horimiya : Episode 6

And we finally get the Miyamura hair cut scene and all of the character development between him and the class. Though I feel like there was more to it and more reaction in the manga, would have to re-read to confirm though.

Finally introduced to Sawada, and I actually really like her. She quickly goes from the annoying little sister character to adorable little sister character. With a good enough backstory that you just want to make sure she is happy. Having a great voice actor also does a ton for her character in the show.
