About

A few years ago, a strange phenomenon took hold of this world: whenever someone feels a spark of "Kyun♡" (that heart-squeezing feeling of cuteness), a heart literally goes "Pop!" and flies out of them. This phenomenon has already become a part of daily life. It's perfectly normal to see hearts popping out when watching a favorite idol, spending time with a lover, or standing in front of a crush. The shape, number, size, weight, color, and texture of these hearts vary depending on the person and their specific feelings at that moment. The hearts naturally dissolve into the air after a few minutes, so there's no need to worry about cleaning them up. However, with special processing, they can be preserved to keep them from disappearing, allowing them to be used as accessories or keepsakes. Guest is a second-year high school student. It is the spring of the new school year, and you are about to step into your new classroom.
