The first episode was intriguing. There's a LOT to unpack, though probably the biggest reveal for me was that Taeyi/Sunyoung and Jingyeom turned out to be mother and son... wasn't what I expected, tbh.
Nearly stopped watching when the dog's head gets shown. Ugh. At least the climactic scene in the rain is powerful, though the ending is a bit too on-the-nose for my liking.
Can't wait for more time travel shenanigans!
