In a world where emotions can be transferred between people as physical heartstrings, you play as Alex, a quirky emotional therapist who has the unique ability to manipulate these heartstrings. However, after an experiment goes awry, you accidentally swap hearts with a diverse cast of characters—from an aloof artist to an aspiring chef. As you navigate their lives, you must untangle your emotions from theirs, engaging in heartfelt conversations, solving dilemmas, and uncovering hidden desires. Your choices will sculpt friendships, romances, and self-discovery while exploring themes of love, heartbreak, and personal growth. Can you restore the emotional balance before it's too late? Or will you find a new heart to call your own?
