Do you have any regret about your first love?
Even if it's drawn beautifully, it's still just your picture book of a first love.

Hatsukoi no Ehon is the third song of the Confession Executive Committee ~Love Series~, focusing on Miou Aida and her romantically unfulfilled high school relationship with Haruki Serizawa. This song and its PV are the first of the song series to be uploaded on Niconico.

The song makes its first commercial appearance on the HoneyWorks Vocaloid album Hatsukoi Note.


The song presents itself as a flashback to Miou's high school days. Here, we learn that she first saw Haruki when he was shouting at one of his classmates down the hall, making a ruckus enough for a teacher to step in. It was at that point when she started to take interest in him, but it wasn't quite love yet. That would come later, when the class notice that the two have become rather close, and tease them about possible crushes on one another. Even though Haruki is somewhat aloof to her, she still has an inkling that he likes her, and is happy about her circumstances.
When they sit together on the steps outside, they ask each other if they have a person they like, and both answer affirmatively, but never say who their favored person is. She ponders about their relationship when she gets back home, wondering if he likes her or not. In the present, Miou-as-narrator curses her own cowardice, saying that if she had pressed a bit further or had been more honest with herself, she probably would have gotten him.
In the last parts of the song, she reveals that she's an adult now, with her high school years gone and passed by. She doesn't regret falling in love with Haruki, seeing him as a treasured first love, but considers putting her past behind her. She never mentions seeing him again after high school, but it's not until later that we find out why.
