Yoake Mae Yori Ruri Iro Na -Crescent Love- and Nogizaka Haruka no Himitsu are both comedical romances which feature similar plotlines in terms of premeditated suitors and a female counterpart which presents an almost perfect image. The males are somewhat different, along with the themes of spaceships but this would not stop one from enjoying one anime if they enjoyed the other.

Both are romantic comedies that has a litany of references to other animes. 'Seto no Hanayome' more often parodying, 'Nogizaka Haruka' moreso paying homage to various animes.
Often emotionally sickly sweet at times, they are fun watches that involves an average but 'honorable' guy meeting a girl from an incredibly well to do family (with highly capable body guards and overly protective dads).
Both girls are relatively air-headed, and both have a 'secret' that must be protected by the guy.
There's also a slight harem and love triangle feel to both, though with both not making it much of an issue.

Cute high class girls who happen to be otaku? This is only one of the similarities between these two animes. Lots of anime references, lovey dovey moments, comedy and a main boy who is just swept up in all of this.

They are extremely similar on 3 parts (apart from obvious high-school lovecom part)
First of all both tells a story of a high class lady falling in love with some unkown student. In both cases it's mutual feeling.
Second of all main heroin is extremely "moe" around main protagonist. She acts very shyly, and is completely vulnerable - which leads to being very happy about slightest complement and really depressed about slightest unsecurity.
Third of all both shows have a whole bunch of secondary characters whos main hobby is teasing the main pair, and trying to arrange them into romantic situations.
The only real differences are the magic elements and more clearly stated feelings in "Mamoru Kun"
