The anime provides a realistic depiction of PTSD and presents a believable, although painful, depiction of the effects the disorder have on personal relationships of those who suffer through this disorder. Takayuki arrives as the ambulance takes Haruka away from the scene and he witnesses the still fresh pool of blood next to Haruka's bloodied hair ribbons laying among the shattered glass of a phone booth as the officer in charge of the scene identifies Haruka from her student ID. This traumatic experience causes Takayuki's PTSD and he is effected more than Mitsuki and Akane. Takayuki and Mitsuki both experience flashbacks, emotional detachment or numbing of feelings (emotional self-mortification or dissociation), insomnia, avoidance of reminders and extreme distress when exposed to the reminders ("triggers"), loss of appetite (Takayuki), feelings of misplaced guilt, memory loss (may appear as difficulty paying attention), excessive startle responses, clinical depression, and anxiety three years after Haruka's accident. Akane suffers from hypervigilance, misplaced guilt, and irritability. Haruka herself is left in a coma for three years and suffers from anterograde amnesia.
