The premis for Oujisama no Kanojo was intriguing, prompting me to take the time to read it. I found the story to be well played-out but at the same time incomplete. It ends rather abruptly with too many ends lefts untied. If you are looking for an extensive complete story then I do not reccomend this manga but if you are alright with an unfinished story then I believe you would enjoy it. The dialogue is fairly believable and the characters are likable. Don't have high expectations but don't completely disregaurd it. :)
