I've never read the manga though I know it's quite popular. When the guy says to a girl, "You're my dog and I'm your master" there's honestly nothing more than that. Call it cultural difference but I'd probably kick someone if they called me their dog. Anyway, since this movie enabled me to get past that cringe dialogue means it was a great one. The premise is cute (minus the dog statement). The cast is cute and definitely passes off as teenagers to me. I am only familiar with the main actor but I liked them all. It's got usual shoujo manga tropes and there's not a lot of depth to the story. Sometimes it is hard to condense the story in a two-hour film so live actions will always let down in some or the other ways. However, it was very funny and had a good amount of LOL moments. Only those who are into shoujo manga/anime/films will love this film since it comes across as silly at times. I also had good second lead syndrome in the last hour of the movie and the main lead was a plain hurting jerk a lot of times. I was okay with it because he wasn't exactly 'abusive'. He was nice to the girl and cold the moment. Watch this film if you're a fan of the manga or just looking for something cute to pass your time. It was worth my time.
