Mai Sohn is a webcomic author who has just been handed a dream commission: write a series about relationships for a major publisher. Inconveniently, her girlfriend has just dumped her. With a deadline closing in and zero inspiration, Mai sets her sights on a complicated subject closer to home, her neighbor Chungyeon. Chungyeon is friendly some days, awkward and weird the next, and the longer Mai spends watching her, the harder it becomes to tell which act either of them is performing.
