No way you actually think the reason Kaido didn't attack Tottoland was because he loved Linlin rather than the fact it was a military deadlock
why did they not think of this alliance prior to the raid?
Secondly, Kaido was worried how destructive an all out war with Linlin + 10 of her pirates which excluded her 1st and 3rd strongest commander. Why would he be scared if King just neg diffs all?
