Yeah it was so cool! I really like the idea of the window glass between them as if it was the physical way to reflect the situation in their relationship !
The way Cirrus was outside in the cold as a parallelism of what his side feel right now and how Skylar is "stuck" inside the room as if it was a reminder of himself before going after Cirrus that-is-to-say trapped inside his inner walls to protect him and his family before going after Cirrus.
The way Skylar is finally in terms with himself and cross the line to be the one who initiate a kiss!!!! OH MY GOSH !!! Perfect I would say!
However I still feel conflicted because they are so destructive when they are together... It feels like the worst part in themselves emerge when they're together ! Thus it doesn't feel right... Idk...
Ch 125 was a masterpiece of a chapter and the kiss during the first snowfall which is believed to make the couple stay together forever in Korean superstitions is chef kiss
