A Supporting Female Character's Daily Life After Transmigrating Into a Book

An Xiyue never imagined she would transmigrate one day. Even more surprising, she had transmigrated into a book.

And she wasn't the only one. Familiar people were by her side, which was probably the most reassuring part of this transmigration.

Probably a modern campus romance. The male lead is a bit of a background character, and the writing is amateurish.
