They're more than likely brothers or half brothers because gio was adopted the only biological parent of gio we've seen was his father who was a piece of shit and after that he was in an orphanage before being adopted by his family he has now so that's probably his biological mom and brother.
Omg, I can’t wait to see where this story is gonna go. Thank you
No problem, I'm really excited to I wanna see gio's reaction when he finds out they're related
I think Felix would be even more pissed off, and gio might spend more time with his half brother trying to bond with him and Felix will be more jealous. I really hope that, that happens.
I can actually imagine that just Felix getting jealous and trying to get gio's attention all the time
HOW DO THEY ALL HAVE AN IMAGE OF GIO.
