Main Characters: Aya and Mitsuki

The romance works because the two leads occupy opposite social worlds while sharing one common language: music. Their contrasting styles also drive the central identity misunderstanding.

Aya Oosawa

  • Outgoing, fashionable high-school girl
  • Gyaru-inspired style and lively presence
  • Drawn to alternative and rock music through the record-store scene
  • Falls for the store clerk before learning the truth

Mitsuki Koga

  • Quiet, reserved classmate of Aya
  • Androgynous style that fuels the misunderstanding
  • Deeply knowledgeable about alternative music
  • More comfortable expressing herself through music than words

The Pairing

  • Aya's direct enthusiasm meets Mitsuki's cool reserve
  • Music acts as their shared language and bridge
  • Contrasting visual styles make the pair instantly recognizable
Identity and First Impressions

The misunderstanding is not played as a cheap trick. Aya's initial misreading of Mitsuki explores how appearance, fashion, and self-presentation shape first impressions — a recurring theme throughout the series.

Music Guide: Where Romance Meets Rock Culture

Music is not background decoration in this series — it defines the setting, shapes character identity, and gives Aya and Mitsuki a way to connect before they fully understand each other. Author Sumiko Arai discussed these creative roots in an interview with uDiscover Music.

Music ElementRole in the Story
Record storeCentral meeting place; where Aya encounters Mitsuki's alternate persona
Rock recordsEstablish the energetic, slightly rebellious mood
Album art and headphonesVisual language that supports the manga's fashion-forward identity
Listening habitsReveal Mitsuki's private inner life and Aya's growing curiosity
Why Music Matters Here

Unlike a standard school romance, this series builds emotional pacing through physical music culture — browsing shelves, sharing recommendations, and listening together. It is one of the strongest music manga in recent yuri publishing.

Beginner Guide: How to Start Reading

1

Understand the premise

Aya develops feelings for a cool person at a record store, unaware it is her classmate Mitsuki presenting a different side of herself at work.

3

Savor the slice-of-life details

School corridors, part-time work, fashion, and awkward conversations matter as much as big romantic beats.

Track the music threads

5

Read in volume order

Start with Yen Press Volume 1, then Volume 2, following the official series listing for new releases.
