Shiori wo Sagasu Page-tachi is a relatively short manga with 10 chapters spread across 2 volumes. It tells the story of how Chitose Tsujikura falls in love with Touka Satsuki while visiting a library. Early in the manga, it is revealed that Touka is hiding something from Chitose, so it makes us (the readers) tense because we don't know what she's hiding or how it will affect Chitose and Touka's relationship. However, we find out that the secret Touka is hiding is that Touka died in the summer, and her younger sister Ayaka has been pretending to be her by dressing upas her, talking like her, and liking the things Touka did (e.g., books and Chitose).

However, after the secret is revealed we can see Ayaka starting to come to terms with her sister's death, as well as learning to be herself again around people. What makes the sisters different is their behaviour, Touka was soft-spoken and loved books, whereas Ayaka can be blunt and isn't too fond of reading but she does so she can talk to Chitose. But, what makes the sisters similar to each other is their love for Chitose. Towards the end of the last chapter, there is a time skip and we get to see how Ayaka and Chitose have changed and grown, and how their relationship is more authentic compared to when they were teenagers.
