Trigger

Mitsui's life has been thoroughly torn apart. And just when he is confronted with the reality that is his life, he runs into his old classmate and former friend Sone. Although years have gone by since their schooldays together, neither one has been able to forget their past: Mitsui rejected Sone for being gay. Now that they have reconnected, Mitsui's only interest is to shame and continue to reject Sone for his identity. But is Mitsui merely projecting...? With complex emotions and a twisted past, Mitsui may also be a victim of his circumstances.
