How to translate「暗戀」to English? 「暗戀」literally means "hidden relationship", but sometimes I found it also means "have a crush on someone".

I am wondering which one is the more common translation?
暗戀 is usually translated as having a crush, the chinese word usually means that the subject being crushed on does not know of it, while I feel the english word for crush can be interchanged with "like / have feelings for / fancy someone"
