Yeah, Cove is the only romance option so far, but if you wait than after the step 4 comes out, a two new romance options will also come out but as DLCs. So, please don't give up on the game yet, you don't have to even have Cove as a romance option, your MC and Cove can always be friends - that's a option too. But if you really dislike the game, I can't force you to play it.
