Kubo-san wa Mob wo Yurusanai Episode 12

Junta Shiraishi has just one goal: to experience youth to the fullest! But this is easier said than done. Junta is so socially invisible that people at school would swear he skipped class even when he’s sitting right behind them. Everything changes when Junta meets Nagisa Kubo. She’s the only person who pays Junta any attention, and her constant teasing is sure to turn Junta’s quiet life upside down because Kubo won’t let him be invisible!
