The last one of six stories from the Kowai Fairy Tale series (コ ワ イ 童話). Each of them is a loose and macabre adaptation of one of the classic fairy tales. This story adapts a fairy tale, "Thumbelina" by Grimm's Brothers. Saeko Machida, a high school girl, has a crush on Yuichi Kimishima, but she was shy and couldn't take action. One day, Saeko receives a red liquid, which is a "love charm", from a mysterious man who calls himself Sakuma in the park. When she put it on Yuichi, his body gets smaller and smaller, and now he follows her faithfully. (Source: MyDramaList)
