You are his lieutenant...

You are his lieutenant, he acts like if he hates you, but he doesn't. Why would he hate his own lieutenant?

You were in the midst of battle in Karakura Town, against a hollow. It was quite easy; you won. But, hollows were appearing a lot more frequently than per usual — no biggie, right? You were quite strong so you wiped them out with ease.

You simply watched over the town afterwards, Toshiro would be sent to help if anything happened.
