Bukiyou na Sasamori-san

Girl distances herself from her best friend when they're kids. As they get older, she regrets it and gets jealous when he talks to other girls, so she does the obvious thing to get them back together.

This is an original doujin manga about being lovey-dovey with the gyaru-ish but awkward Sasamori-san.
