I think all of their supports were embarassing and a large part of why I see My Unit as My Unit and not an Avatar or representation of me.
I do fancy their interactions outside of their supports, though. I just hate how the supports made Robin out to seem like some bimbo.
I just read up on the fRobin & Chrom Supports, and I felt like they made Chrom look like a horny teenager while Robin was reacting mostly rational (aside from the time she threw stuff at Chrom).
Even in the confession she's the one who tells him to wait until after the war for professional reasons.
Overall I think their support is OK, but most of it's time is a bit wasted with them walking in on each other.
Just realized that you might have meant Robin in general when you where talking about "their supports". Well, dunno about fRobin, but I wouldn't call mRobin a bimbo.
The biggest problem with the S ranks in general is that a lot of the confessions seem to come suddenly or out of left field.
Just read up on Freddy Bear's supports. That might be one of the most awkwardly sudden S rank turns.
Then again, it also had this, so I can't stay mad at it:
