You play as a quirky medical intern in a hospital where hearts are literally exchanged based on emotional compatibility. Patients come to you with varying degrees of love and heartache, asking for a 'heart swap' to reignite their passions or escape their unsatisfactory relationships. As you navigate through a series of hilarious and often absurd situations, you must match the right hearts to the right people while managing your own chaotic love life. Your choices influence not just the patients' fates, but your own search for true love. Will you be a heart hero or get lost in the complicated web of emotions?
