Hmmm, I have a feeling that the client is lying as he is way too angry for someone who is supposed to be grieving.
I bet either he killed someone and want to have a convenient excuse or found an extremely valuable corpse.
It ends? Aw, shucks.
A manga with an interesting premise ends like this, and shit manga like Rent-a-Girlfriend continues.
People truly do have shit taste.
NGL, if I were ever in her situation, I would be nothing but a psychotic, murderous being that kills everyone that have the slightest of malicious intentions toward me or my loved ones.
