But she finds it hard to find a guy that meets her criteria, and she writes down her worries in a book cafe notebook. But when a man she doesn't know writes her a biting reply, the two begin to exchange messages. When she meets that man, Takahashi, she begins to rely on him for some reason as she sorts through her feelings for her ex and the new man she's been seeing.
