From StarryHeaven:
Jun has always liked the super popular and hot Kazumi-kun. However, he always has girls competing for his attention. So when the newest issue of a shoujo magazine comes out, she buys it for the furoku (freebie): a paper charm that you write your wish on and put under your pillow so that itâll come true. Her wish? To be with Kazumi-kun. She doesnât expect the charm to work anyhow, as sheâs never had any luck with them. To Junâs surprise and delight, in the morning she wakes up to find that sheâs friends with Kazumiâbut in a boyâs body!
