Tons :D
Personal suggestions: I don't know if it counts in the shojo spectrum, but Blood Lad is funny (action/shonen too) with some comedy romance in it.
A SUPER 流行的 one is Free! too. 你 can check that out
There really are tons of comedy/shojo 日本动漫 (those categories are always perfect for each other aha), so I suggest going down a 列表 like this of 2013's Summer shows
link Just see the previews on any that interest 你 :)
