I cant help but feel like the ending was kinda...rushed???

not just "kinda" it really was rushed

it was! some chaps were dragging it out, the others just unbearably short, but the rushed ending is kind of their theme i believe. dan has no self respecc- if he did, he would've let jaekyung suffer for at least a year before ever looking back. the rushed ending reflects how dan's heart sways every single time he interacts with jjk.
