In a world where hearts can be physically exchanged, you play as 'Melody', a quirky heart merchant dealing in emotions. After a freak accident at the annual Heart Festival, your heart ends up in the possession of a grumpy but charming stranger, Axel, who desperately needs it to mend his relationships. As you navigate humorous and dramatic interactions exchanging hearts with quirky townsfolk and dealing with love triangles, misunderstandings, and emotional dilemmas, you'll uncover the true meaning of love, empathy, and what it really means to have someone's heart. Each choice matters as you build connections, resolve conflicts, and redefine the very essence of heart.
