These are also known as little booklets found with the purchase of the albums of BTS, in the Love Yourself Series and the Map of the Soul Series. It contains small journal entries, often as an introduction to the upcoming books, HYYH Notes 1 and HYYH Notes 2.
The Love Yourself Series[]
The Love Yourself series is also indicative of the Love Yourself timeline. This is the first fixed timeline after the many time loops caused from the Save Me Webtoon and the BU Story. It is separated into three: Her, Tear and Answer. These three note sets intertwine to form the storyline in combination to the HYYH The Notes 1 post April 11 Year 22. They do also contain histories of the character.
Map of the Soul Series[]
The Map of the Soul Series is indicative of the Map of the Soul timeline. This is the second fixed timeline, continuing from the reset of the Love Yourself timeline. It is separated into two: Persona and 7. These two note sets intertwine to form the storyline in combination to the HYYH The Notes 2 post April 11 Year 22. The booklets of this timeline, unlike the novel, contain small snippets of the history of the characters.
