No, it doesn't. I only reacted to "weird". Who would considering anything happening between those two weird? My definition of weird is the ending of Usagi Drop or something similarly fucked up. I wouldn't consider something happening between Kouhei and Kotori weird, so you don't need to worry about me spoiling such development or lack of it.
And like I said, there isn't too much of the manga out, so nobody aside from the mangaka would even know any real spoilers. This anime couldn't be much longer than this cour or they would run out of source.
But yeah, I'm sorry if I made you feel like you were spoiled. I'll try to be more careful in the future.
