Hemm...THIS IS REALLY A HARD QUESTION! ahahahhahahaha
I actually love the Two Wolves and Their Son. The story simply amazing and I felt it's filled with errmmmm...Otona-poi no kanji? (Adult taste feeling) The story actually filled with a sense of humor between the two working daddy and I just love man with suits!
ahahahahhahaha...The other story also great too...I just love it..
Another my Favorite is Doukyusei series with Sotsugyosei as the sequel of the series. The story? LOVE! I love the slow pace of sweet feeling between the two of the main character. It's giving like...err.. pure love? ahahahahahah. I love that too!
Darling! also my long last favorite. I always read it over and over again! ahahahah...the story just fit with the love and lust of young people! Yuzuha Ougi Sensei works always erotic ahahahahahahahhah!
Akhhhhhhh~ I felt so hard to choose the best favorite! Almost of all the story I love...but I really hope Darling series will be continuing to be present to us...please scanlated it more. ahahahhaha
