Des:I had a childhood friend named Hiyori that I hated. One day when I returned to my parents house for the first time in 10 years after failing to get into university or finding a job, I happened to run into that troublesome Hiyori again... Hiyori, who had become a CA, was beautiful and truly the flower of Takamine. And before I knew it, I became addicted to Hiyori and couldnt live without her...even though I should have hated her...
