Billy-bl -

In early 2026, Billy made headlines by publicly addressing his sexual orientation.

Billy recently transitioned from his previous management at to a more independent path.

Billy supports Babe's new venture, an artistic platform focused on music, performance, and fashion. If you'd like to dive deeper, I can look for: His full filmography beyond the major BL titles. Specific interview translations regarding his coming out.

The couple has been vocal about responding to "toxic" fan behavior and rumors, choosing at times to be more private to protect their bond. Professional Transitions
