Mayonaka no Orphe

Kazushi, a 30-year-old man, struggles with insomnia and PTSD, his sleep constantly disrupted by nightmares that medications and therapy fail to ease. After collapsing at work, his coworker Wabuka discovers his condition and uses his soothing voice to help Kazushi sleep without nightmares. Wabuka then proposes they live together so he can continue assisting Kazushi at night, and the two begin a shared living arrangement. Their unusual cohabitation involves sleeping in close contact, a situation that becomes increasingly meaningful to Wabuka as time passes.
