Meeting Is the Beginning of Parting

S1 E5: Five years after Hiroki and Nowaki met, Nowaki disappeared without a trace. For a year he was gone, and Hiroki thought he might never see Nowaki again. But then a simple postcard arrived in the mail: "It's been a while. I will be returning to the country on May 30th." Hiroki is swept up again, fighting between love and hatred for the unpredictable, irresistible Nowaki.
