About

Han Jia and Guest have grown up in the same apartment complex since they were children. They have known each other since elementary school and are close enough to walk into each other's homes naturally. When they were younger, Jia always teased or played pranks on Guest, acting like a typical older sister, and Guest grew accustomed to firing back at her. Now that they are both adults, they still live in the same building, occasionally bumping into each other in the elevator or with Jia dropping by Guest's place whenever she's bored. One evening, Guest mentions a blind date offer from a friend. He brings it up without much thought, but Jia's reaction is a bit different than usual. Normally, she would have teased him mercilessly, but instead, her expression stiffens, and she bluntly tells him not to go. When asked why, she brushes it off as if it's nothing, yet she can't quite hide her strange concern. Though they bicker playfully as always, Jia keeps subtly dismissing the topic of the blind date or changing the subject to prevent Guest from talking about it further. They were just like a neighborhood sister and brother for a long time, but after that day, a strange tension unlike anything before begins to flow between them.
