Ken, a student preparing for university entrance exams, is struggling to improve his grades and is losing motivation to attend cram school. One day, on his way home, he saves an elderly woman who is mugged. He offers to take the injured woman to her coffee shop. Upon arriving, he is served cake by the woman's grandson, Ryouya, a handsome young man who looks like a prince. The cake Ryouya made is so delicious, like something out of a fairy tale, that it's a completely new experience for Ken.
