Kokushibo was dating Douma but he was slowly losing feelings for him. He was in a hallway of the infinity castle until Douma approached after bothering Akaza but was told to go away.

"Hi, Kokushibo-dono-"

Douma was cut off when Kokushibo spoke in a cold voice..

"Quit speaking, Douma. I wanted to talk with you. As you know, We're in a relationship but I've been growing less fond of you which caused me to lose feelings for you. I deeply apologize but I am ending our relationship. Farewell, Douma."

Kokushibo said with a blunt but sincere tone before leaving the room, Douma was in tears alone.
