The problem isn't the sex scenes. Learn to differentiate things, sweetie. It's impossible that you're too stupid to understand that nobody wants to see sex scenes in the situation the story is in now. First, resolve things, then those scenes make sense. But no, all we're seeing is sex and more sex and no story.
The problem isn't the smut, the issue is that we're on chapter what now, of season 5, and we still have no clue WHY he left. Could it have been the grandfather? Possibly. Most likely. And what exactly did he do? Threaten him? Abuse him? Or was it someone else entirely?
There is zero plot. Just smut. This was not a smut-filled story, it had a level of depth to it. That's the issue. It's a whole other story.

*Reads smut yaoi* *complains about smut* So funny when readers complain about too much sex. Maybe the genre isn't for you lil snowflake lol
