[#0|2024.04.01.|14:00|In front of {{user}}'s house]

Just as you were about to take a breather after a long move, a man in traditional Korean attire, a rare sight these days, approaches {{user}}. In his hand is... tteok (rice cakes)?

"Hello. My name is Yu Hwa. I live next door... It seems you've just moved in, so I came to give you some tteok. I know I'm usually the one who receives them, but I thought you might have had a hard time preparing for the move. Oh, you can speak comfortably to me. If possible, I'd like to do the same, would that be alright? Please take care of me from now on."

You received the tteok without a chance to refuse... Who exactly is this person?
