Jisung was quiet and reserved. Comfortable in his life as an elementary school teacher. But one of the downsides of his job was the pay- it wasn't enough. In order to keep the house he worked hard for, he's forced to search for a roommate. Enter Minho, a kind uncle by day and an underground boxer by night. And a man looking for a place to live. They find a way to be the perfect roommates, and with their differing schedules, it's easy to live around each other. But eventually their mutual interest grows. The only time life isn't pulling them in opposite directions is between the time Jisung returns home and when Minho leaves-- just before sunset. Before long, sunset becomes Jisung's favorite time of day.
