Hey darling,  
                       You’re the oxytocin 
                                     The love hormone 
                          Creates bonding, trust 
                                            And attachment 
                   I’m addicted to you 
                            You travel through my brain 
                                                       And spinal cord 
 
                                         Hey darling,  
                           You’re the ventral tegmental area 
                                  Produces depomine 
                                                   Induces the feelings of pleasure,  
                           Want, craving  
                                                   And motivation 
 
                                         Hey darling,  
                              You’re my frontal cortex 
                                      Disrupts my judgment and planning 
                     Blinds my smitten 
               Causes my serotonin to drop 
            I cannot control my mood,  
                                                     Emotions, sleep 
                                                                           And appetite 
 
                                        Hey darling,  
                        You activate my adrenal glands 
                            Increase my cortisol 
                                     Release my nor epinephrine 
                                                  I feel excite 
                                                          My heartbeat recites 
 
                  Hey darling,  
                     You’re my testosterone 
                          Together, we purify our chemistries 
                             Of love 
                                 On this Valentine’s Day
