What an AVERAGE way Koiko goes!

Synopsis

Normal equals happiness! ...At least, that's what she thinks.

Koiko grows up watching her love-struck mother and her loveless older sister. She doesn't want to suffer by drowning in romance, nor does she want to be pitied for having none. So she chooses the safe route—an average boyfriend and an average high school romance. But when she gets involved with Tsurugi, the most popular guy in school, her "normal" happiness begins to fall apart?!
