Tsuzura-senpai wa Motokano dakara

Osanai Ritsu has one simple aspiration for his high school years: a quiet, uneventful existence where he can blend into the background and never be troubled by drama. He dreams of calm mornings, peaceful afternoons, and a life perfectly free of chaos. Unfortunately for him, reality has a different plan. The one person who poses the greatest threat to his tranquil ambitions is none other than Tsuzura Sana, a popular and strikingly unpredictable upperclassman—and the girl he once dated in middle school. Their past relationship is a secret Ritsu would rather forget, but Sana seems to have no intention of letting him move on. With an irrepressible nature and a knack for catching him off guard, she charges back into his life, turning his orderly world upside down with her relentless antics. As his "ex-girlfriend" reappears as a constant presence in his daily school life, his carefully laid plans for peace are utterly derailed. Caught between the embarrassment of their history and the bewildering whirlwind of her attention, Ritsu finds his resolve tested at every turn. She teases, she meddles, and she refuses to take his desire for silence seriously. In this uproarious romantic comedy, the battle lines are drawn between a boy who craves solitude and a girl who embodies delightful chaos—and for Ritsu, a normal high school life seems further away than ever. With an ex like her, who has time for peace?
