It's a romantic comedy. It's gonna get a bit confusing at first. Just wait until あなた meet Renge... But trust me, keep watching. It'll make sense later. あなた won't regret watching it. I convinced my friend who doesn't even watch アニメ to watch half of the first episode and she finished the entire series in a 日 and she loved it. Plus, it has bishounen ♥
It makes sense if あなた pay REALLY close attention to everything that happens. There's a hell of a lot of foreshadowing. Half of the stuff at the beginning of each episode only makes sense at the end of it. It's kinda weird, but it's funny, cute and awesome later in the series. :3
あなた decide to watch it cause of the flat chest pic? LOL, its pretty funny, gets もっと見る interesting when it goes into もっと見る detail about the characters. But its really aimed もっと見る for the female audience.
Oh Ouran.~ Well, since it is a reverse harem, it may just not be your thing (sorry to categorize here, but usually males don't really go for that genre). However it's really funny, and I think it pretty much just goes uphill from the first episode.
