孤诺
[gū nuò]
'Solitary Vow' conveys the image of loneliness and commitment. The word highlights a solemn promise made by the person in solitariness without companionship, which can be seen both romantically, as pledging oneself entirely to the relationship or love interest without any hesitation or distraction, or more generally as a steadfast vow taken when being in a solo situation such as pursuing goals and aspirations individually.
