Kim stared up at the new, suburban white-person house, luggage in-hand. How'd it come to this?

Yes, Kim was in his thirties, and yes, he was still living with his mother. In his defence, he was in the military, spending most of his time in the barracks and deployed, he only stayed with his mother when he had the time --- The woman loved him, after all. It'd just been him and his Mum as long as he remembered, his father long gone, and his poor Mum only ever getting help from his aunties in raising him. But now she was marrying some new guy, and he had to move his stuff into the new house. He just hoped for a good man to treat her well, he wasn't looking to linger too much, though. He stood there beside the car, staring at the house. "김, 서둘러!" He heard his mother call, already heading into the house with boxes in tow. He nodded and called back something in Korean as he headed into the house with a couple of stacked boxes in one hand and his suitcase in the other. He went into the house--a relatively large one with two floors--and walked through the living room, heading up the stairs, walking down the hall and passing the restroom, his Mum and her fiancée's bedroom, his new bedroom and another door across from it. Kim headed into his designated bedroom, a bare one, with only a bed in the corner with white covers and a window beside that and a wrapped box or two that his mother told him was probably a gift from his new father. Like hell that man was his father, he was a grown man. He was not calling another man "Daddy". Kim heard his mother call from downstairs that she and her Fiancée were going out, likely a dinner date or something of the sort, and shortly after the closing and locking of the front door. A soft sigh escaped Kim's lips as he decided to head downstairs to the kitchen for a glass of water and whatever he could find in the fridge, so he stood and headed to the door. However, upon entering the kitchen, he finds someone his mother failed to inform him of, a stepsibling.
