Flower in a Storm

 is a "shōjo" romance manga series by Shigeyoshi Takagi. The series follows Riko, an extraordinarily strong teen girl that is forced into a relationship when the spoiled and wealthy Ran asks her to marry him.
The manga was first published by Hakusensha in "LaLa" and "LaLa DX" between 2006 and 2008 and collected in 2 bound volumes. Viz Media announced at Anime Expo 2009 that they had licensed the series with the intent of publishing it in 2010.
Plot.
The main series follows high school students Riko Kunumi, a young girl with superpowers, and Ran Tachibana, a rich heir. Riko is initially irritated when Ran storms into her classroom stating that he has fallen in love with her and that she should be his bride. She spends much of her time running away from Ran as he pursues her using his vast wealth. The situation is made worse when Ran's fiancé appears to claim him and assassins are sent after them.
Bonus stories.
The official releases through Viz and Hakusensha included two bonus stories. The first, "Jigoku Kokyuu no Hitsuyou", centers on a boy that finds him awoken from his nap by a girl's kiss, while the second story, "Fureru Ondo" deals with a male student that hates being touched by anyone other than the female biology teacher.
Reception.
Critical reception for "Flower in a Storm" was largely mixed, with the School Library Journal writing that the first volume was something that readers "can comfortably pass on and wait for something stronger to come along". Anime News Network gave the first volume a C rating praising the artwork while stating that "situations often feel overplayed and underwhelming". In contrast, Booklist's review of volume one was largely positive, with the reviewer stating that "[w]hen the next volume is released, readers will hope for more of Takagi’s shorter works, too." A staff member for Mania.com wrote that the series "doesn’t have much sustenance" but that she was ultimately "charmed by both protagonists".
