Here's the corrected version of the text:

"Ugh, painful," I said while holding my sore muscle.

It was a good fight with Dalv. I learned new things while fighting him, such as not relying too much on muscle memory, since it's too lazy.

I wanted to talk with Dalv, since apart from being a good adviser, he was the same age as me, so I believed it would be a good small talk, but he was busy.

I looked up at the sky, and although it was still bright, I was very sleepy. I was exhausted, more than at any time in my past life, and I didn't regret it.

I went to a tavern to sleep for the night. The next day, I took a shower and ate some fancy food. I also cut my hair, since it was getting too long. It was a calm day, just like it was supposed to be.

I was walking in the street towards the guild to get my new ID. It was a bit busier compared to yesterday, or so I thought. Just for a treat, I bought some snacks to eat along the way.
