Nishina got married but was divorced soon after. During a business meeting, he saw his true first love, Miyama, who didn't seem to recognize him. They have been lovers during high school, but Nishina didn't think it was something to pursue until the future. For him, Miyama's love was burdensome and it intimidated him to realize that they wouldn't be normal. Anyway, he said the harshest words to say to someone gay, especially to someone who loved him. 10 years later, in the present, Miyama didn't expect to see him again, unchanged and suddenly barging into his life. Here, Nishina insensitively tries to get back with Miyama. Even if Miyama has lingering feelings, he doesn't trust Nishina's intentions and believes that he'd walk out on the relationship again.
