Haha! Well, it's both of them really. Leander is "oops, no, sorry" because he makes the BIG ERROR and lets his family down, gets replaced by someone he considers lesser than him, and then eventually has to learn the error of his ways. Bram is "oops, no, sorry" because he doesn't want to be King and is always messing up his princely duties because he doesn't know what he's doing.
EDIT: Maybe the "oops, no, sorry" thing is actually way more accurate than the real three words I wrote looking at it haha
