I'm not sure about Darvey happening. The writer has implied on numerous occasions that its platonic.
(which pisses me off but ive kind of come to accept it)
I would maybe feel different about M/R if they were more consistent but sometimes i barely feel like we even see their relationship. IDK i guess its a preference thing because they just really do nothing for me and are one of the most boring tv couples ive ever seen.
But suits to me isn't really about the romance.
