If you didn't watch the after credits scene... Shino was waiting under the cherry blossom tree for Tsuda and when he came out of the school she called to him and the both walk up to each other and Shino says something to him and blushes but there is no sound.
I read manga only~ so there high probability she do confess or say something silly~ add Tsuda lvl of density he may misunderstand thing~ again~
95% of the so called "movie" is taken from the manga, 1hr+ long so that would make 5 episodes joined together into 1 episode. They should just make another season.
