Today I'm recommending Kininatteru Hito ga Otoko Jyanakatta by Arai Sumiko.
What we have here is basically a nice Sapphic love story. The girl on the right is a super popular gyaru type, while the girl on the left is an unassuming background looking character. HOWEVER, she works at a music store that her uncle runs that just seems to be frequented by the girl on the right. When she's working at the music store, she's super hot (no joke), so she develops a crush on her without even realizing who she is. However, the girl on the left knows it's definitely her. Read as their bond begins to deepen from a misunderstanding and an enjoyment of rock music.
So yeah, I highly recommend this. It's sweet, it's cute and it's all around a fun time.
