Maybe boarding school? And its over and he wants to come back
That make sense. Although I dont feel like they were apart so much seeing Potato always hanging around the house looking for uniforms or when boss watches him play hockey or motorbike races. Joined at the hip literally ╮(￣▽￣)╭
Yeah, just a guess, but i dont think its this either (￣∇￣") could be an overseas opportunity that boss made him go, or boss just bought him a house and dropped him there (in a good way, not to mess with him)
I wonder if they got separated at some point in the past? Especially with Big Potato asking to live together 'again' hmmmm
