Pronoun and の adjective
おれら
ごめん。 俺らがこの会話をするのは明らかにすごく早すぎたよな。でも、ただ、俺はお前と結婚したいと思ってるってこと、言いたかったんだ。
I’m sorry. It’s obviously way too early for us to be having this conversation, but I just wanted to tell you that I want to marry you.
I with a ら on it makes it plural. It's less formal than 俺たち (if you've seen that word yet), but has the same meaning. It's we.
The reading is the same as the kanji's reading.
