Good for her for keeping her promise or whatsoever. She still slapped a corpse, in front of friends and relatives. I wonder in which universe "Oh yah sHE wAs jUsT KeePiNg Her pROMise. No NeEd TO be OffEnDeD by CorPSe SlaPPiNg. JuSt a PrOmIse, HomIes" will be the normal reaction... especially given the cultural background of Japan. But hey, you are entitled to your own opinion. Just saying people displayed by Kana's actions are very sane.
I used to like Kana in the beginning lol, but seeing her slap a corpse in front of the family is disgusting, she's selfish and unlikeable, thank god his adoptive mom stepped up cause had it been my son I would have done more than a slap
