@Varler the authors shown hints for a while now they're not capable of keeping the original premise down so now it's going off the rails while putting in things for entertainment value.
Sachi is no longer Sachi nor has she had the character development to be this way first the bug then asking for murder. She desperately clings to Mister yet tells him she never trusted him. What a waste of Misters efforts on her. Honestly I think double suicide at this point would be a better end to this then for the author to keep wrecking the beautifully interesting premise it started with.
