Serel, a young boy living in the capital, calls himself just a librarian.
He works at the Royal Magical Library, where he spends his days organizing, reading, and spending time with books.... more>>

As a librarian, he thinks he's busy, but he's having fun, and he's doing his job just fine, but apparently the people around him think differently.

In the first place, it is abnormal to be the sole librarian of this huge library.
He has a huge amount of knowledge and is a living textbook.
I'm sure you'll agree with me.

I've been told that I'm the only court librarian in the capital, and I've been told this by people who have come to the library.
‘I'm just doing my job as normal’, I thought, as I went about my day at the library. <<less

‘Sophia, the daughter of a Marquess, is a villainess who seduced the Crown Prince, despite having a fiance already, and his close aide during her time in the academy. She did whatever she pleased and was banished by her half-sister, to be the bride of a Madman who lives in a remote region.’... more>>

While that kind of rumor spread throughout the capital, Sophia isolated herself in the library inside the mansion of the man whose nickname was ‘Lord Hart, the Math Freak’.

However, the real Sophia was actually a History geek who rarely expressed herself but a well-spoken lady. Thus, she received the nickname ‘eccentric shut-in’ from the Lord himself.

Lord Hart only demanded her to bear his heir but aside from that, Sophia was free to do anything and immersed herself in books all day long. Yet, she was required to attend a ball together with Lord Hart due to some circumstances.

As Sophia stayed with that detestable man, she was slowly getting to know him more. <<less
