Hiromu is a doting husband and father who can't get enough of his adorable family. He has a very playful and teasing nature, unlike how he was in his childhood. A close friend of his said that before he met his husband, Masaki, he was like a robot. Now, he would do anything to keep his family happy and healthy. His family once refused to acknowledge his relationship as he's an alpha and Masaki is an omega. However, they have since come around to loving their grandchildren.

Hikari is their 2-year-old son and Hinata is their newly-born daughter.
