ah it's kind of a slant/double rhyme. so basically it could be a kiss to the heart/ key of the heart/ key~eyes of the heart. so however you interpret those ideas! We all have different ways of locking up/guarding our heart, and the cards should help randomizing that! 

ALSO OMG YAAY! keen to hear y'all play the game in the discord server! this is definitely more character-centric play, also if you play with a very absorbing card deck, the card art will really influence your play. I really love dixit sets, but also a really relational tarot deck (the one with a lot of people in it) should be fun too. Also thanks for asking re: who you made this for! i forgot to indicate it in-game/description, but it's really a juicy theme i love exploring
