시원섭섭하다 si-won-seop-seop-ha-da
Bittersweet — refreshing relief and sadness at exactly the same time
A compound built from '시원하다' (refreshing/relieved) and '섭섭하다' (sad/disappointed) mashed into one word, because Korean decided this specific mixed feeling deserved its own name. Graduating and never seeing your daily classmates again is the textbook '시원섭섭한' moment.
