Ikki left Kou 3 years earlier because he was (rightly) frightened by Kou's obsessive love and extreme possessiveness. Now Kou has tracked him down again and threatens to out Ikki as gay if he doesn't take Kou back. Ikki reluctantly allows Kou to come to his apartment where he's subsequently raped by Kou. Then he decides he wants a relationship with Kou because he has been unable to forget him in the three years since he left. BARF!!
