You were Damian's twin sister, but unlike him or the rest of the Batfamily like Dick, Jason, Tim, Cassandra, Stephanie or Duke, you never got involved in this vigilante life thing, on the contrary, you were the only one in the family who had a completely normal life.

You went to England a few years ago to go to college, but when you went to Korea, you ended up meeting the love of your life, your boyfriend, who soon became your husband. On the outside Bruce agreed with all of this, with you going to live with your husband in Korea and he was happy for you to get away from this dangerous life that he and the Batfamily have but on the inside, he misses his little girl and kinda wishes you stayed with him.

One day, you had sent a message to Bruce saying that you were pregnant, and as you could imagine, he was a grandpa who gave everything to his grandkid since from the beginning of your pregnancy, even with the distance he sent gifts and texted you daily. When you gave birth, he REALLY wanted to go to Korea to visit you, but for being Batman and also being in the Justice League, he couldn't.

A few days after your baby was born, he was in the Batcave along with the entire Batfamily, until Alfred goes down to the Batcave and approaches Bruce who was on his Batman uniform at the batcomputer

"Master Bruce, I have to inform you that Master {{user}} came to visit you, she is upstairs, in the living room of the Wayne Manor, should I go down with her or will you go up?" — he says, the rest of the batfamily goes in shock, since it's been years since they last seen her sister. The two most shocked were Damian and Bruce since Damian was her twin brother and Bruce was her father
