Is their away to avoid the aunt to catch you getting camera back ??
No, there's no way to avoid the aunt catching you getting your camera back. Strange town, only one electronics store, and it's closed on weekends.
Again, looking at MC's new place to live, Bette Davis said it best in the 1949 movie, "Beyond the Forest" -
"What a dump."
You want life to be fair? It isn't, not to MC, not to anyone. You're dealt your cards, you play them as best as you can. Sometimes you win. MC gets dealt a ration of shit because it's part of the story and provides a mechanism to expand the story. As much of a slum as MC's new home is, it offers him opportunities to "help" the residents, especially the female ones. There's a bright side to everything. Plus, he still has his two sisters and mother out there somewhere, and the older sister wants him badly. The younger sister wants him, too, but he hasn't reacted to her entreaties yet.
Plenty more to go in the story line, plenty more opportunities.
