Having characters pining for each other in what they believe to be unrequited love is also something I like, as well, and when explored in different ways it can lead to some good crunchy angsty stuff. I'll try any flavor of this trope. The "pining while already together" is one that I've come across that I found to be really enjoyable. I discovered this through an arranged marriage/marriage of convenience fic and the way it was done just made me realize that I love the concept of characters who have to be convinced that they are worthy of being loved by someone who think could never, ever love them for who they are, because of the arrangement of the relationship. It really is about that headspace about them denying while pining, the self-loathing, the the acceptance of the love the other has for them.
