Well damn. That was a powerful story. The dialogue errors and mix-ups were annoying (the coffee shop scene had a very confusing one) but not a huge deal overall. The creepy parts had just the right amount of suspense, not jump-scares like I was expecting, and the plot twists towards the end were mind blowing as well.
Without going to detail why (spoilers would ruin the suspense and "mind-f*ck"), I honestly preferred Ending 2. Either way the reader chooses, it's a sad but sweet tale that makes the characters real and tempts another read-though... Much respect to you!!
