What an AVERAGE way Koiko goes!

For Koiko, true happiness lies in being perfectly ordinary. Growing up, she closely observed the romantic lives of the women in her family and drew her own careful conclusions. Her mother constantly lost herself in overwhelming love affairs, while her older sister lived a bleak existence entirely devoid of romance. Determined to avoid both extremes—the pain of drowning in passion and the quiet pity of having none at all—Koiko resolves to walk the safest path available. She sets her sights on a completely average high school relationship with an equally unremarkable boyfriend, convinced that this carefully calculated mediocrity will guarantee her lasting peace of mind. However, Koiko’s meticulously planned life takes an unexpected turn when she becomes entangled with Tsurugi, the most popular boy in their school. Far from the ordinary partner she envisioned for herself, his presence threatens to unravel everything she has worked so hard to maintain. As her carefully constructed vision of a normal romance begins to crumble around her, Koiko is forced to confront whether the safe route was ever truly the key to happiness she believed it to be.
