I would have given 10 if there was a little more intense story, then it could have been better. I mean ML suddenly fell for her out of the blue within an episode after he accidentally kissed her forehead and started flirting suddenly. it would have been nice if there were more romantic encounters before he realized that he actually fell for her and started to develop feeling for a girl whom he considered to be his sister (even attended P&T on behave of her original brother) THAT AWKARDNESS IS MISSING!!! and then try to avoid her but finally give in to his feelings for her...something like that would have been nice. other than that there is romance and the story is pretty good but the anime version of this was on another level so my expectations were high. TBH I didn't like the fact that ML's background story is something that almost all typical C dramas and Kdramas have. it would have been nice if at least he was an orphan and that girl who followed him around was a stalker or something like that instead of a debtor who is behaving like a psycho with no self-respect, that was kind of awkward to watch.
