上伊那ぼたん、酔へる姿は百合の花

New university life, new dormmates…and a whole new world of drinks! Botan Kamiina takes her first sip of alcohol after spotting the quiet dorm leader, Ibuki Tonami, enjoying a highball alone. From shochu to whisky, Botan shares the joy of drinking with friends, while Ibuki slowly learns that some pleasures are better when shared.
