I know tht feeling. @-@ just finished reading it all now too
I'm glad you loved it and lived through it! Some people find reading OP daunting because of the chapters. I'd say they missed one hell of a great story. For me, 700+ chapter for this awesome series is too short and the story is just getting started.
I....I finally finished it
I read all of one piece
All the feels
All the chapters
Everything
........what do I do now (·_·)
