I have been crying a lot with One Piece in those past few years, even strongly sometimes like the ending of Kuma's flashback, the reveal of Shogun Momo, Toko and Yasue. (whole cake is a whole other level of tears)..
But this.. I legit couldn't stop sobbing and I'm now stopping myself from reading panels because it only takes one little panel to bring me to tears.
This emotionnal pay-off is crazy. For me, it's on par in term of impact with "I want to live", "Help me", "I still have my Nakama" or the departure of Vivi.
