I unknowingly read the spin off to this story first (the one about the abusive ex). It is probably just as well I did because in that one he was dealing with the memories of hitting his ex which is bad enough. But in this, the extent of the abuse was pretty extreme. From pulling hair to choking to burning with a cigarette to hitting... it was awful to read what Yumi put up with. The only redeeming feature of the ex was that his actions were abhorrent even to himself so he ended the relationship for both their sakes. Once the MCs got together in this story it was so nice to see Yumi with a protective and gentle guy.
