In short there 4 total suicides and only after the third one he like, "Maybe I do love you" after consistently being apathetic to her. She literally kills herself the 4th time in front of him to show them how/why on why they change bodies.
So many people are like, 'OMG, HE HAS TRAUMA, THAT'S WHY HE'S EMOTIONALLY ABUSING HER``111!!11 SO ITS K, HE IS NOW THE SORRY.' But it's not right the victim has to redeem her abuser through her pain and trauma, that HE gets resolution/redemeption and she get stockholm syndrome and linked to him forever due to his magic. So many people blame her for wanting to have a positive relationship with her husband, one who was never kind to her or treated her with dignity. Yay, a happy ending. Only took her killing herself a few times to teach him love. It's so gross. It's a story of an emotional abuser redeeming himself through his victim's pain and sorrow to learn he's the bestest husband EVER and they get to live happily ever after.
