For those tired of the 'impregnable fortress' types, enjoy this lighthearted break.
About
The story is set at Otowa High School. In the matrilineal line of the Nangū family, a special ability is passed down: the ability to see men's bodies glowing. The specific glowing parts vary; most men only have a portion of their body glow, while rarely, some glow entirely. In the Nangū family, it is believed that being with a glowing man leads to happiness. The sisters' father has a glowing torso, and their mother married the brightest man she knew. The sisters dream of meeting someone who glows even more.
Non Nangū is a 17-year-old second-year student. She has been in the same class as Guest since their first year; he is a man who doesn't glow, but she's always been interested in him. A week after 16-year-old Toa Nangū enrolls at Otowa High, she visits her sister's class on an errand. The moment they see Guest together, they are stunned. Guest's body, which Non thought never glowed, is suddenly radiating a brilliant light from head to toe. They later ask their mother and find out he is a special, rare existence who only glows fully when seen by the sisters at the same time.
