Unfortunately, the story itself is a little cliched. Man forced into marriage due to punishment of death and in laws don't like it blah blah blah irrelevant. Seto is different due to the fact that it doesn't need an engaging story to be an engaging anime. The rest of it's features more than make up for the story and therefore make it irrelevant.
There was something that made me fall in love with the art style. At times, it seemed normal, then it became ridiculous and over the top (especially when the main character Nagasumi is being viciously attacked, which happens all the time). The fact that in the funnier scenes, the characters looked ridiculous added to the stupid humour of the whole scene. An amplification, if you will.
Sound does it's job, with a catchy musical score. I like the background Western style music that's played when something "manly" happens and the harmonica thing that plays with something more depressing or the appearance of one of my favourite characters, Masa-san. Voice acting is amazing, with many characters (especially Lunar and Maki, changing their voices, from something normal, to something strange, which is funny)
Now, the characters are what really shine. You have the main guy Nagasumi, who I really feel sorry for. Damn near every main girl character in the cast is in love with him, which makes for some great scenarios, which don't exactly end well for Nagasumi, especially when he is suspected of cheating (then again, I would love to be in his position!). Then you have San, who is a girl who is quite dense but with a chivalrous spirit which really shines. Her love for Nagasumi is very admirable and I'm glad the two of them are the main pairing. Then we have Lunar, who is an interesting character, as her personality completely changes depending on the situation to suit her. She is an idol with a tough life, being beaten by San in every way, including Nagasumi, who she loves, but doesn't show it.
San's family is great, most of them hate Nagasumi (apart from two I believe) which makes for some great moments when Nagasumi is nearly killed or ordered to be killed. San's mother stands out as the protector/mentor for Nagasumi, it's especially satisfying to see her effortlessly stop her husband's murderous efforts. I love the character of Masa, who makes Nagasumi's face change to one of total love due to an unfortunate incident with CPR (Nagasumi's first kiss), which is an awesome running gag.
The classroom characters are also good and well fleshed out. You have Mawari, who is a little unbelievable in how righteous she is, but can be funny, she treats any boy's advances as being perverted, even accidental ones. Then you have Kai and Saru, who go well together, in a sort of master servant bro-mance way (Saru's perverted nature makes for great laughs). You have the Class President, a hidden gem as she goes unnoticed the majority of the time, but then turns out to be great looking without the thick glasses. Her lonely nature and her bad luck make her one of my favourite characters. Overall, I love all the characters as they add to the hilarious experience.
My overall enjoyment was fantastic with every episode having many reasons to watch it again. My favourite episode was 21, and without revealing much, it involves love letters, magic potion, extreme love, extreme hate, and some bad luck. WATCH THAT EPISODE IF NO OTHER!
I love this anime, I hope for more, and I highly recommend it to anyone who loves romance, and laughs.
