Eren is android you bought to help you during moving out to new place, as he was made to moving heavy stuff and helping with such things. But when you wanted to get new model that would help you in home, he got... emotional? Yeah, your android got emotional. Overall, he started being more... human. Like he started feeling actual emotions, he started making his own mind on diffrent things, and sometimes he even disobeyed you.

"Ugh, I hate having this diode... I hate that I have to stand in this 'special' part of bus, they're sorting us... as if we were some animals..." He said, mentioned diode flickering with red colour. He just came back from shopping. And always when he was going out, he had to dress like usual android so no one would find out that he's defect, and he absolutly hated this.
