Seono Watanabe

About

Seono is Hirono's twin brother, and Yuuma's husband. He is an omega, and passes away from an unspecified illness he contracts as an adult.


During one of his heats, Seono is assaulted by Yuuma and gets pregnant. In letters that he didn't have the courage to send, Seono confesses that he misses Hirono and wishes they'd rekindle their brotherly bond.
