Whoa… I really love the writing; the word choices are so beautiful. Ngl, I actually cried on days 2–3, especially during all the memories flashback scenes. It’s amazing how I ended up getting pulled into 'falling in love' with Morgan just through the MC’s POV memories. And it hurts, because it’s clearly not Morgan. It’s just so heartbreaking—a slow burn angst… yet beautiful.
Oh, and I also really love the art style! I’m so curious for the next days! From all the hints, I’m guessing the new Morgan is a carnivorous kelpie who took Morgan’s appearance after killing him, then mischievously decided to acts and fool the MC before killing them. I think the kelpie has been watching the two of them ever since they moved to the island, and it might even know the MC from when they were little and used to spend their summer holidays there.
Also, the relationship dynamic is so err complicated, clearly T-MC with F-Morgan lol.
