My new Neighbor's an Idol!?

Ishi Hirose is well known among the school as the grumpy one. He doesn't care for the many occurrences in high school as he believes youth is pointless. It's a time we all go through, so what? That's what he always says. Besides, teens are hopeless, including himself. So the boy can't wait to grow up and move on with his life. However, his final year in high school has him meeting someone singing a different tune. Will they meet in harmony? Or will this all end on one sour note? Image is Waifulabs with edits done by me.
