Boku no Kokoro no Yabai Yatsu: Love Comedy ga Hajimaranai

The main character is Kyoutarou's older sister, Ichikawa Kana... commonly known as Onee! She has lots of female friends, but of course she doesn't have a boyfriend!! Featuring that older sister, this is a regrettable romantic comedy that seems like it's going to start being a romantic comedy but doesn't!!
