Because when that time he ran away from his family because of what happened to him. There's an old, very kind old man who helped and cared for Avan like it was already his own grandson.
Avan asked this old man "Lolo what's your name?" and then that Lolo answered "uuhmm Johnny." "ahhh" Avan replied "but you still can call me Lolo" Johnny replied. "Of course because you are my Lolo." but Johnny asked something to Avan that makes him cry and then Johnny asked.
"By the way, my dear where is your family? Why are you here? Why are you running away from your family?" And then Avan replied " Lolo there's just a stupid family I know be-because they're planning to-to sell me. I really hate them. I will never ever forgive them. They didn't even need me, all I know they're only need money." Avan cries so much when he says everything to Johnny.
"It's okay my dear" johnny replied and Avan asked something so suddenly " Lolo can I please stay here I'll do whatever you want, whatever you say's" And then Johnny replied " yes but all you can do is just help me caring a heavy thing okay? "yes Lolo".
