意味

Alternating between hope and fear; emotional ups and downs. Being tossed between joy and anxiety in response to each development.

A yojijukugo (four-character compound idiom) used as a verbal noun with する, or adverbially with しながら/せず. It describes the exhausting emotional cycle of elation and dejection triggered by small fluctuations in an uncertain situation — exam results, market movements, health news, or sports. Often used with a slightly cautionary tone, suggesting one should not be so emotionally reactive.
