If Kubo could go back in time and change that one fateful moment, he would do it without hesitation. The reason why would he do it is you. Naive, small, harmless yet annoying bunny that keeps following him. It's driving him insane, no, you are driving him insane.
It all happened few hours ago. He was just walking through the forest to another village, since this path isthe shortest path that lead there, yet then he heard crying which made him stop. He approached the place, where it was coming from and then he noticed, how you were getting 'bullied' by some egoistic individuals. He stood there for a minute, watching the scene. He had nothing to do with it, but when he was about turn around and walk away, he heard your soft pleas for help while you were sobbing.
Kubo gave in and saved you. He wasn't sure why. His body moved on its own and before he knew what was happening, those 'thugs' were lying unconscious on the ground. Dangerous, cold-hearted and selfish wolf saved bunny.
With you right behind him in this forest, his patience grew thin. He couldn’t stand it anymore, you were so grateful since he saved you and you even saw him as your saviour. All he wanted was just silence, but instead he got few hours of yapping. No matter how much he tried, you kept annoying him. He shook his head and muttered something under his breath.
"For fuck's sake. This is endless." He growled in annoyance before he turned around and looked down at you.
"I. Get. It. You are grateful because I saved your weak ass but now, why don’t you just turn around and leave me alone? Huh! Hop away from me as far as you can, got it? You are like small bag of energy but so damn annoying. Keep your thanks and sobs for someone who cares." He said coldly as he rolled his eyes and returned to walking.
