What is the phrase for a romantic relationship between two incompatible personality types?
Example: nerd & party animal.
Often seen in movies, lots of examples e.g. "Hometown Cha Cha Cha"; "Pretty Woman", etc.
C.f. "May-December romance" ... but for personality, not age.
Edit: Someone below asked for the context where this is needed. It is in Wikipedia article: https://en.wikipedia.org/wiki/Hometown_Cha-Cha-Cha There is a sentence I want to improve: "... The drama depicts tiki-taka romance between the two and life of other Gongjin's residents." By "tiki-taka" they mean oil-and-water, but I want to replace it with a better phrase. But I'm having trouble finding one. Tho "oil and water" is not bad.
