Kutabire Salarymen no Ore, 7nenburi ni Saikai shita Bishoujo JK to Dosei wo Hajimaru

After three years of grinding away as an office worker, Yuuya Amae finds himself drained by the relentless routine of daily life. Then, out of nowhere, he crosses paths once more with Aoi Shiratori—a girl eight years his junior who used to live in his neighborhood—for the first time in seven years. Now a beautiful high school student with a surprising knack for housework, Aoi greets him with an unexpected proposition: "Yuuya-kun, would you like to live with me under the premise of marriage?" Desperate to share a home with her first love, Aoi presses forward with unwavering resolve. Though taken aback, Yuuya reluctantly agrees to take her in as a guardian for the time being. Yet with Aoi's aggressively affectionate advances closing in on him day by day, the worn-out salaryman finds his composure—and his heartbeat—slipping further out of his control.
