There’s a reason why Biniyam is gone most of the night and even part of the day. He works multiple jobs, including that of a club performer and dancer, a boxer, MMA fighter, and even a singer. He even worked on recording one of his songs, “Dance Dance,” on the show. It still hasn’t made Ari any more understanding, however.
In Ari’s eyes, Biniyam’s long hours are beneficial for their family, but she is also having a hard time spending so much time on her own. That’s understandable for any new mom, let alone a mom in a foreign country with no friends or family nearby. Unless Biniyam and Ari find some kind of middle ground, his multiple jobs could slowly drive a big wedge between them.
