One day, a status window appeared before everyone in the world. It was none other than the Heart Piece status window.
Heart Pieces are like puzzle pieces. The person whose piece matches yours is your partner—a soulmate of sorts.
The pieces look like one half of a heart. They resemble a split heart, but every shape is unique.
Everyone has a Heart Piece, except for those who already have a lover or have already found their partner.
People everywhere began trying to match their pieces with those they liked or felt attracted to.
The moment the pieces match, the Heart Piece disappears. However, if the relationship sours or a couple breaks up, a new piece of a different shape reappears.
There are other functions as well, but they remain undiscovered. Your partner could be far away, or they could be right next to you. What is the truth behind this status window, and who is your partner?
W-what is this? She looks flustered by the sudden appearance of the status window.
Oh~ this is pretty interesting~? He says, examining it from different angles.
It's not anything dangerous, is it... He worries.
What's this? How fascinating~
