In the sense either the the other lead has to accept that the lead's ambition/occupation will always come first, which he/she accepts, maybe because the other lead has the same ambition but not the skills to fulfill them. 

Or, where one of the leads are simply eccentric and they have to accept that and that the other lead's love for them might be there or not from one moment to another. 

I guess, in simple turns I'm looking for a romance where love is valued on opposite terms, yet finds away to be in a relationship either way. 


Things I've seen that kinda fits:

Flower of Evil (haven't finished it yet) (https://mydramalist.com/54625-flower-of-evil

Brain (https://mydramalist.com/3067-brain

Here is my attempt at recommendation (I’m saying attempt because I haven’t watched TOO many dramas that are like this so yeah I’m just trying I don’t know if my recommendations will work lol)

Himizu - This is a movie but I think the main relationship is a lot like this.

Six Flying Dragons - This is a drama that has a lot of different things going on in it’s plot, but the main romantic relationship in this is JUST like what you are describing.
