Naoko Yanagi

She is a teacher from the middle school that [Nasa](https://anilist.co/character/130944/Nasa-Yuzaki) had frequented. She is always super busy with work and doesn't have much time for her life. However, once she sees how happy [Nasa](https://anilist.co/character/130944/Nasa-Yuzaki)'s marriage is, she becomes more open to future relationships. She considers herself a boring person.
