I'm not sure if these count so I'm putting multiple
"Tell me, you fool. If I continue to regress, will I ever get to meet you again?"
"Then I'll keep writing the epilogue for you until the end of time, for eternity."
"Eat the soil, Yoo Joonghyuk." (This one is significant for reasons only novel readers understand ((I saw spoilers but I'll get to that chapter soon trust))
And others "Sunfish bastard", "I don't think that love here means the love between man and woman necessarily.", "...Why does he call your thing a 'Black Flame Dragon'?"
There might be more that are better suited for this but I think that's enough
