Synopsis
Nene and Kou want to learn more about their mysterious friend, Hanako-kun―and what better way to do that than school mystery number five, The 4pm Bookstacks!

The rumors say that a secret door in the library leads the way to a supernatural special collection. The Bookstacks know everything about everyone who's ever attended Kamome Academy―past, present, AND future!

But whatever you do, don't read the red books...or your future will be drenched in blood!

The Donuts
Hanako wondered if Nene was acting weird as she used to whine a lot while cleaning the toilets. Nene said that this was how she usually acts and asked Hanako whether the absence of whining was a plus. Hanako said that it was rather boring and forced Nene to look at him. Afterwards in class, Nene thought that she was indeed acting weird. Ever since looking at Hanako's past self, Amane, she could not look at Hanako the same way. While gardening, Kou showed up, praising Nene for tending the garden and asked if she could make donuts.

When inside the Home Economics Lab, Kou said that he did not know how to cook. When asked by Nene, he said that he wanted to make donuts because his little sister begged for them. Nene then tells Kou about how she felt about Hanako. In the end, Kou also told her how he felt about exorcising Hanako.

When the donuts were done, Teru appeared and asked if Nene was making donuts too, she said that she helped because Kou said he was a bad cook. Just as Teru was about to reveal that Kou was actually a great cook, Kou shoved a donut into Teru's mouth and packed some donuts in a bag, telling Nene to give it to Hanako. Nene went to find Hanako, thanking Kou by calling him Kou-kun instead of Minamoto-kun.

Nene found Hanako on the roof and gave him the donuts. Hanako gets excited, saying that he loved donuts and was also glad that Nene was back to normal. Nene told Hanako how she felt and decided to stay friends with him. As Hanako was about to tell Nene the truth, a black paper crane flew out of the donut bag. Hanako defeated it by using his knife. The torn crane exploded, causing a plume of smoke to appear. A supernatural, Tsukasa, appeared in the smoke, implying that Hanako would protect Nene yet he had killed him.

An exchange diary, or koukan nikki, is a diary shared between friends or lovers. Each person sharing the diary will take turns writing down their thoughts or feelings, knowing full well that other people will read it - kind of like Facebook without the internet. Like Facebook, all of the writer's friends who are in a position to read the "feed" can comment on posts/entries. In the case of lovers, only the couple will see the entries, but this diary is even more private than that, as she is playing the role of both writers.

Setsubun is a Japanese festival to welcome spring.

During this time of year, it is customary to cast out demons in order to welcome a peaceful new season. This has led to a tradition of having people wear an oni demon mask, and others will throw beans at them to "exorcise" them.

As mentioned in the previous volume, the Japanese writing system uses ideographs, so by telling Nene what other word to find the kanji for the name Amane, he is in effect telling her how to write it.
