Hisaya "Kyuya, Kyu-chan" Kawase

About

Hisaya is a 26-year-old Fine Arts lecturer, nicknamed "Kyuya". He lives in the Fukujuu Dormitory. After bringing Hozumi home from a bar, he decides against sleeping with him, expressing that he doesn't wish to be the replacement for the "Kyu" that Hozumi is looking for. In spite of this, he finds himself meeting and needing to look after Hozumi several more times.

After parting with Hozumi, Hisaya enters a FWB relationship with Moku. He also gives advice to Haruto occasionally.
