Haeseon is a career-focused woman who puts work above everything else, while Seonho is a quiet homebody who prefers spending time with his cat. They couldn't be more different, and their lives were never supposed to overlap.
But everything changes when they're assigned to the same task force team—and to make things even more awkward, they find out they're next-door neighbors. As they get caught up in each other's daily lives, Seonho's first love suddenly reappears, turning things even more complicated.
Can these two complete opposites survive the chaos and maybe even find love along the way?
