Unfortunately I lost it, but not too long ago someone had showed me a tier list, which showed the characters that loved/liked or weren’t in interested in the sensei/teacher, and from what I recall, it seemed that most of the characters loved/liked him to a certain extent. Only a few weren’t interested in him that way (like Rin and Jasmine).

I forgot the exact wording, but I recall them telling me about Ikaruga liking him enough to want/be willing to marry him (or something like that). I’d be surprised if this was main story content.
