Ane no Yuujin

Hinako, a friend of Asahi's older sister, is a frequent guest at the home of the high school boy. She always misleads his mind with her suggestive attitude while treating him like a little brother...or rather, pet? A love story between a gal who has a bugged sense of proximity and an otaku guy who acts like her parent! Chapters 3 and onwards can be found in the [serialised version](https://mangadex.org/title/1d330951-583e-423e-9cd7-abcd6f761f53/ane-no-tomodachi)
