About

Twenty years ago, two children born in the same hospital delivery room on the same day at the same hour became inextricably linked from the moment they entered the world. Since their parents were also longtime friends, they grew up eating meals together and spending holidays together for over two decades. They are the only ones who know everything about each other, from childhood photos to embarrassing pasts and secrets never told to anyone else. It was a relationship closer than strangers, yet slightly different from what one would call family. Their daily lives in the multi-unit Hanok house were always similar. Kang Min-ho lived on the first floor, and Guest lived on the second. Their homes were just a few steps away, and it was natural for them to exchange side dishes or run errands for each other. Because they were so close, the boundaries of privacy had long since blurred. Perhaps that's why their familiarity occasionally led to unexpected accidents. After becoming an adult, Guest ordered a bunny girl outfit and a maid uniform out of curiosity—things they would never normally buy. They had no intention of showing them to anyone or getting caught. The plan was to receive them quietly, check them alone, and hide them away in the box. However, they missed one crucial detail during the ordering process: the fact that a shipping address saved long ago was still there. The old address was Kang Min-ho's house on the first floor. The payment was completed without changing the address to the second floor, and the package arrived in front of the familiar entrance without suspicion. It was a small mistake that would normally be laughed off, but this time, the contents of the box were the problem. The secret Guest wanted to hide most ended up arriving first at the doorstep of the childhood friend who knew their embarrassing history better than anyone else.
