To outsiders Karin appears to be a normal, cheerful high school student. However, Karin and her family are all vampires. To make matters worse, Karin is not even an ordinary vampire - she is a blood maker and must inject the excess blood into her victims! If she doesn't find a victim to bite in time, her extra blood is expelled in the form of a massive nosebleed. Karin's already difficult life is made worse when Kenta Usui transfers into her class and she finds her blood increasing at an alarming rate. When sharing classes and an after school job together make avoiding Kenta impossible, Karin must find a way to keep her rapidly increasing blood under control or risk exposing her family's secret.
Both Karin and Orange Marmolade are vampire themed romance series. Both of them feature a vampire girl in a high school setting. In both cases the girl tires to blend in and not attract unwanted attention from her human classmates. Those series also feature a vampire family who supports the female lead. I think, I don't need to mention that said girl's love interest is a human boy. The style of those series might be a tad different, but if you liked one of those, the other one should still prove interesting.
Both are romance stories about a vampire girl who tries to go through life without attracting attention to herself. The girl then falls in love with a human boy and the story unfolds from there.
I'd say Orange Marmalade is less comical, and rather more serious. It's also the better of the two by far, but if you like vampires and romance then each of these should hold your attention!
Mei Tachibana has had neither a friend nor a boyfriend in 16 years, and she doesn’t plan on ending that streak any time soon. The outcast learned years ago that social obligations only lead to pain, and has carefully guarded her heart to keep from getting hurt. However, the girl can’t stay withdrawn forever, especially after attracting the attention of the handsome Yamato, who finds her caustic personality interesting and strives to date her after she roundhouse kicks him down the stairs. But even the most earnest of romances can be crippled by jealousy and insecurity, and this pair has plenty of both. Can their feelings for each other overcome their own emotional weaknesses, or will this love perish before it even begins?
A quiet, unpopular girl stumbles into a chance encounter with the most popular guy in school, who just happens to be extremely good looking and admired by all the girls. Mr. Popular then takes a shine to our lonely heroine and their romance blossoms from there....
While Orange Marmalade follows a vampire girl, Suki-tte Ii na yo has no supernatural themese whatsoever. It does, however, take things a lot farther with regards sexual thoughts and acts than the former. But if you enjoyied one then the other may be something you'll find interesting.
