Around 30 Chan (2014)

Original title: アラサーちゃん無修正

Arasa is at a crossroad in life between popularity and ego. Arasa is suddenly invited, by her ex-boyfriend Oraora (whiz of Charai event management company), to join a party of sex friends. The party includes: Mihiro (a cute lovely girl), Taishu (an average boy), Yaririn (head hostess with a loose crotch), and Himote (publisher, who wears men's glasses). Hitome is left uncomfortably behind, but she ends up in love. (Source: wiki.d-addicts)
