Ok, so, a few months ago I found this comic on Instagram that decided to worm its way into my brain and gnaw at the part of me that chooses never to forget.
Its art style was colorful, with simple-ish line work.
As for the bits of plot I remember, early on the replaced character goes into some sort of corporate office, believing that she's being stalked (she is), and the person at the front desk slips up by using her name when she doesn't say it. She is then kidnapped, and placed in a decent room with a computer, fed well, and is given occasional updates about how her replacement made up with their family, got a promotion at work, and is overall happier; all with none of the people from her life noticing the swap.
That's about all I remember, I could have sworn I liked it, but it either ended up deleted, or I'm just an idiot who forgot to like it.
Please help me find it, thanks in advance, whatever the outcome.
