Man, the way you wrote down the subtle breakdowns that each character had when MC went missing and subsequently returned was wonderful. It was cathartic to see them quietly break down and it was only Callie who had such a reaction (I mean like, the poor kid lost their older sibling on their birthday!) and the fact that you could feel not only the confusion but longing in MC's narration hits close. I like the scenes where it feels like MC is almost like a stranger even though they shouldn't be, and I'd love to see more moments where MC is submerged in the ice cold waters of reality and how many precious moments they couldn't have with their own precious people. I mean, if it was me I'd have my mental health at a very low score just from that realization.
I also squealed when I saw the poly option (ngl I thought of our cat before realizing it was a mash up of Alex and Grayson lmao) and now I am fully curious how it'll turn out. I'd still love to be close friends with Kennedy!
Also, with the inclusion of the dad I'm wondering if he had anything to do with MC's sudden disappearance, especially when it was a sci-fi so I'm curious if the dad's work coincided with MC. The mystery itself is thrilling, I'm looking forward to what happens!
