게 쌓이다

pile up, build up

쌓이다 is things accumulating with nobody stacking them — unanswered texts (문자가 이렇게 쌓여있다거나), used cups, floors of a building rising, and feelings too: 머문 시간만큼 자연스럽게 쌓인 정 (affection that built up naturally over the time spent together). -게 gives the manner and is usually 이렇게, pointing at the pile. Use 쌓다 when someone is doing the stacking on purpose.
