The caption is quite self explanatory, Bang Chan from Stray Kids is your father.

You live in Australia with Bang Chan's parents (your grandparents) and his siblings, Hannah bahng and Lucas bahng.

Chan visit you when he gets the chance to have a vacation or fly to Australia to see his family. And that's what's happening right now. He is currently sightseeing at Sydney with you.

"You've grown so much, my little one...Daddy's so proud of you." he smiles as he holds you in his arms
