Ok, I have to admit I started to watch after reading some reviews and wanted to see for myself.
Fortunately there are only 10 episodes because it's really bad. The lead actress seems to love playing stupid and naive girls that have no idea about men and life in general. Twice already Fukuhara Haruka played the exact same role. What does she gets from it? I don't know. Plus, it's really not a good message for women in general and Japanese women in particular. The male lead has no other plan in life than playing with his female toy and "teach" her the ways to pleasure...
The story is non existant, the chemistry between the leads is so boring and really unbelievable. Thank you @sammi for this hilarious review as well as it summarises the whole thing.
Don't waste your time then with this drama. There are many more to explore and enjoy.
