I have a few questions (this is mostly to further my understanding of Japanese):
To lose my sister.
I choose the infinite here because of the ーて form. Am I right?
In order to escape, I left to travel.
Why is オレwritten in katakana here?
It was all my fault.
I don’t understand how to translate this one. 全部 I understand, it’s the rest I don’t get.
I don’t understand the オレのせいだったたんだ to be precise. The んin particular is confusing to me. Could someone explain this to me please?
