Osananajimi ga Zettai ni Makenai Love Come Manga Cover Volume 1

My childhood friend Shida Kuroha seems to have feelings for me. She lives next door and is small and cute, but I already have my first love, the beautiful idol of our school, Kachi Shirokusa! I should have no chance with her, but while walking home from school, she only talks to me, even with a smile!

I might have a chance, or so I thought. Then I heard that Shirokusa already had a boyfriend, and my life worsened. As I was drowning in despair and depression, Kuroha whispered, ‘If it’s that tough for you, then how about we get revenge? The best revenge ever.’
