From Evil Flowers:
In Japanese, Oyayubi Hime literally means Thumb Princess, but it is also the name used for the classic fairy tale Thumbelina. Our heroine, Kogami Madoka, is talented at massage (ie, she has magic thumbs), earning her the title of Thumb Princess in a different way than Thumbelina. She’s always giving free massages to her friends and one day she finally gets the chance to massage the boy she likes, Matsuoka. But, he runs away from her like he’s been touched by fire. Rumors say that Matsuoka hates to be touch by girls and he’s even violent about it. Will she be able to melt his heart with her “magic fingers”?
