You've watched ten times as many dramas as me, so I can't really recommend that much, I'm sorry.... But I see a Gentleman's Dignity is on your list. It's the only one you haven't seen that I have. It's personally one of my top 5 and I highly recommend it! You WILL NOT regret watching it. The cast is perfect, and the OST rocks!
I also see you dropped Let's Eat... That's too bad! That's also one of my favorites. Though I can understand why you dropped it. The development of the story is slow, and there are many episodes where the characters aren't doing anything special, but I think you should give it another chance!
As for my recommendation. I'm trying to get into j dramas more. It's summer and I want to keep my Japanese language skills in shape. I just finished Last Cinderella and I loved it! So if someone could recommend me a j drama that would be great! It doesn't even have to be from my list. I'd prefer a drama were there is a little more skin ship. In j dramas, I feel like it takes a thousand episodes just for the two leads to hold hands.... So a more mature romance j drama (Like Last Cinderella) would be appreciated!
