Help finding manga (yaoi)

Read this years ago and want to reread it but forgot the title

- highschool, both guys are bickering type bsf
- light haired bottom (A), black haired top (B)
- notable memory: B has a thing for stockings
- A is a track runner
- A accidentally wore his sister’s stockings to school, and B found out
- vaguely remember the cover being a blue sky and A and B on it
