A shy eighth grader buys a magic mug at a mysterious shop and accidentally summons a love fairy who grants wishes. What could go wrong immediately does. The show trades heavy stakes for the actual chaos of wanting something badly and having no idea what you're asking for, watching a kid learn that every wish comes with a price that isn't death or despair, just awkwardness and consequence that somehow matters more. By the end you're invested in whether Kaede figures out what she actually wants, not what her panic brain wished for at three in the afternoon.
Kaede stumbles into a curiosity shop and buys a simple cocoa mug that changes everything. Following cryptic instructions etched inside, she summons Mirumo, a mischievous blue fairy from another world. He's supposed to help her win over Yuuki, the boy she's hopelessly crushing on, but Mirumo has other priorities: chocolate, pranks, and absolutely anything except actual romantic assistance. What starts as a comedic clash between Kaede's genuine feelings and Mirumo's chaotic indifference becomes something deeper. The fairy prince isn't interested in playing by the rules of the human world, and Kaede learns that getting what you wish for requires more than magic. As she navigates middle school crushes, friendship drama, and her own insecurities, Mirumo's presence forces her to grow beyond the girl who relied on a shortcut to happiness. Blend comedy, genuine heart, and fantasy adventure into a story about wanting love and learning that the real magic happens when you stop waiting for it to find you.
