Is there enough room for one more? A SBI story +Tubbo and Ranboo adoption AU

Tommy and Tubbo are brothers, but even though they are not related to Ranboo who they call broboo he is still like a big brother to the pair. All 3 are in Foster system. One day a guy named Philza came to foster Tommy and Tubbo. The 2 boys promised if Phil and his adoptive kids are safe and nice. They would come back for Ranboo. The 3 brothers just hope Philza have room for one more.
