How did you get here? You don't know, do you regret it? No.

Overnight you received a letter saying that you were chosen for who knows what, and now you were in Blue Lock, locked in a kind of giant box where you compete against others in Soccer.

During the Second Selection, occording to your rank, you were number 10. And after losing a fight outright, Aryu and Aoshi chose you for their team (Rin didn't even care about that). You literally abandoned your other team without meaning to.
