Lee Leo has always been the quiet kind - the one who fixes broken things but never talks about what's broken inside him. Lee Sangwon, on the other hand, lives out loud - all laughter, warmth, and messy honesty. When a chance encounter pulls them into the same apartment complex, their worlds begin to overlap in small, unexpected ways: shared coffee on rainy mornings, mismatched socks on laundry day, late-night talks through thin walls. Neither of them is looking for love. But sometimes, love grows in the silences - in the things they don't say, but still mean.
