Jun-ha' has been appointed as a librarian at Namsan Library.

On the first day of Joon-ha's appointment, he meets 'Summer', who lives hidden in the library.

Summer died in Namsan in 1999, but a special existence that remains as it was at the time. The secret to such a summer to maintain its human form is reading books.

If you feel emotions while reading a book, you can think and act like a living person. Even Summer, who seems like an ordinary person at first glance, has one peculiarity: Summer cannot interact with people born after 1999, when she died, or objects made.

However, Jun-ha is an exception.

Junha was born after he died, so why can't we see each other? Summer thinks that Joon-ha is the key to reincarnation, and tries to entice him into a book reading group.

However, Joon-ha is not interested in Summer's proposal.

In the meantime, he finds out that Joon-ha had a relationship with Summer in the past.

Go, as Summer's reincarnation, reveals her dark past

I hope to see that it can be corrected.

This is how the two people's Namsan Library Reincarnation Book Club begins.
