Lately I have finished reading Living-room Matsunaga-san, personally I enjoyed it. ₍^ >ヮwith Ryu, and him being fixenated to Miko.
Since 9th volume it seemed to me like the story was longer than it should be and for me it lost its sparkle. It didn't hurt the story in any way to the person itself. Even though this was a lil bit turn off for me I woud say, I still recommend it and I think its wort it.
but thats only my personal opinion ~

PS: the scenes where is only Miko and Matsunaga are the best! give it a try!
