My Powerful Neighbor, the Husband on Her Marriage Certificate

【Workplace romance + marriage before love + mutual devotion + the powerful one humbles himself + seven-year age gap】【A gentle, slow-burn sweet romance】 To deal with her grandmother pressuring her to get married, Wen Nian followed her wishes and impulsively married her best friend's eldest grandson. Their prenuptial agreement read: 【After marriage, we will live separately. We do not need to meet unless necessary, and any meetings must be arranged by phone.】 She thought a marriage certificate wouldn't disrupt her peaceful life. Then a transfer student joined her class, and the student's parent turned out to be her upstairs neighbor. Even more surprising, ever since the student arrived, the school administrators had grown friendlier toward her, the scumbag who had been pestering her was inexplicably transferred away, and whenever she ran into trouble, it was resolved right away. Her best friend said she was on a lucky streak. It wasn't until one day, when she accidentally found a marriage certificate at her door, that she discovered her husband was the mysterious neighbor upstairs, the transfer student's parent. Then one day, Wen Nian attended a teachers' conference. Why did the impressive senior official speaking confidently onstage look so much like her husband? Was she seeing things? 【Content warning: The male lead is not divorced. His comrade sacrificed his life for him, and the male lead adopted the comrade's son to repay that debt.】
