Am I mixing things up because it's been so long?

I read the novel and afaik when Dan disappeared (current) there's a scene where Chunyoung was just randomly standing in the midst waiting for someone (which is Dan) he don't recall. Then the snow falls and all aarghhh that really messed my eyes up, it was a painful scene for me. This current disappearance overall hurts so much (っ˘╭╮˘)っ
