Here's the English translation of the passage you provided:
---
My conversation with Dad ended just like that a few days ago. I didn't feel that anything was wrong at all. Yeah... even so, I kept going through my days cheerfully with my friends. I wasn't bothered at all by the topic Dad brought up back then.
I spent my time at home just staying in my room. In fact, I only saw my parents during meals or accidentally around the house. I know this isn't good for a parent-child relationship. But I'm just a teenager on the journey to adulthood, and what I want is their understanding. Yes, just the word "understand."
In the journey of adolescence full of teenage troubles, I try not to start any conflicts. I'm just too lazy to deal with problems, even with my friends.
