Renai Chuudoku (Mikage, Tsubaki)

It's not male bonding, it's "animal ♂" bonding. Once the spider, Shiori, met the beautiful and gentle butterfly, Midori, he fell in love. However, Midori is "feed" to Shiori. A love that cannot possibly have a prayer… The other bugs in the story include a cicada that was born merely a week ago and his unrequited love, a camouflage bug that crosses their path… And what about the bugs who shoulder many difficulties and their earnest pure love!?
