I left for a couple months to build up some to binge read and not only was there not a lot, but there's been no character development for joo. 50+ chapters and we still know nothing more about him and there's no change to his behavior. There's been no growth in either main characters or their relationship in all this time. That slap was quite epic, but if there's no development by the next time I come back in 2 or 3 months, I sure won't be finishing it. And after such a great, promising start.
