I recently started watching 2 Moons and I'm very surprised by how good it is. The main character is OMG super cute. I find the slow development of romance (they're jerks to each other) to be very endearing.
Love Sick was one of my first BL shows and while it's not the best one out there, it's incredibly sweet.
I'm also enjoying Love By Chance, but at this stage, I think I like 2 Moons more.
