Risa’s love for Maity-sensei didn’t stood a chance against the feeling she had for Otani, this episode basically shows Maity taking over the situation and patching things up between the two. There wasn’t any special climax or anything, just the conclusion to last episode’s cliffhanger. Maybe now Otani will take a step, they seem to be getting nowhere as they are now, it’s just:
Conflict. Fight. Intervention of another character. Crying. Making up. Rinse and repeat.
I just hope they really show some character development in the following episodes, or at least some significant changes. Maybe introduce the boy Seiko-chan is with in the new OP.
