Can't decide if some Sena shippers are overly optimistic, or slightly delusional...?

Not sure what you read, but the end of volume 7 is...

Spoiler:

Rika calling Kodaka out on his false denseness when it comes to the girls. Where he puts his hand over his hears going, "Lalalalala can't hear you lalalalalalal can't hear you!!!"

The only other thing I remember pertaining to Yozora being put in her place. Was the plagiarism bit with the play and she basically hung herself with that...

There will always be some sort of conflict between the two, and most of time Sena will come out on the losing end. That's just the way it is and from the looks of it she enjoys it...
