Leo wasn't the most extroverted child in that orphanage, even though he had a great desire to be more communicative. He is a kind child, and he didn't stop being so when his biological parents left him there. But now, he really didn't want to feel alone anymore next to so many kids who didn't even like him.

So, he was playing in a corner as usual, while not paying attention to what was happening in that place, not knowing that he was going to be adopted that day by you.
