Hatsukoi Monster

the plot of the animes are completely different from each other but some aspects of both anime are similar. (for example: living in dormitory, rich girls ....) the character design of main anime characters look alike Kanade - Miketsukami Kaho - Ririchiyo however Inu x Boku ss is way more better then Hatsukoi Monster 

In this series, there is a relationship with a kid, A gir of high school with a boy, with something different 

Both are comedy animes that take ridicoulous ways to entertain the audience. 

The same story plot where it involves ordinary girl surround by fairly oddball guys.  

So, in most ways they may not be the same, but plotwise they are since both have that indirect lolicon theme behind it. However unlike Shounen Maid, the lolicon theme of Hatsukoi Monster can qualify as a reverse lolicon (if we can call it that way) while Shounen maid has that usual lolicon thingy except it was the shounen who has balls to control his uncle (were I suspect has some lolicon thing for him). But in Hatsukoi, the kind of lolicon was that of a teenage girl acting as the guy's nanny. 

-Both have the same type of immature humor -They share a lot of seiyuu in common -The characters don't have similar designs, but they act similar 

Both Anime Have 11-year-old boy Look ways Older than the age. In Both anime a high school girl fall for the main lead guy.  

Both anime are for female audiences Both anime start with a twist Both anime features a reverse harem Both anime have a weird sense of humour 

It involves the MC in an drom , where he/she is in love with someone in the dorm, whom were proving to be quite a hassle. What's worse was that them MC were surrounded by weirdos. The difference, in Bokura the weirdos were a mixed bunch of people whom were quite unpredictable, while in Hatsukoi, most of them weirdos, have a lot of sexual innuendos within them.
