SPOILERS! SPOILERS!
This movie felt to me like they edited out the scenes that would have made the movie make sense, any scene that included any time of emotional development between the characters.

Yamashita Tomohisa as teacher Sakurai Haruka - he kept all the crazy girls at bay, and falls in love with a girl that has no emotions whatsoever? They've never had a conversation with one another, but he loves her? He's gorgeous, that's all I got from him.

Komatsu Nana as Kururugi Yuni - she was the most immature, mature young lady ever. She hates him but she loves him? She's never shown any emotion at all, yet she's going to confess in front of the whole class? Did she love him because he talked to her about English? What's the attraction!?!? This character was the epitome of robotic. They might have been portraying her to be on the spectrum, but if so, this movie would have been so much better if they had addressed it. I think it might have been to show that only he saw her "inner emotions" because she clenched her fists. She's beautiful, that's all I got from her.

Don't even get me started about how, even though they have never been on a date, he wants to marry her.

I did like how the evil troublemaker was one of the teachers and not one of the kids, though why there always has to be an evil troublemaker, I have no idea.

I would have enjoyed it, I think, if we were given any insight into why they loved each other.
