Himawari wa Yoru ni Saku

Sunflowers are blooming at night

Norihito and Asumi Hisato have a beautiful marriage. But when Norihito makes a mistake at work and the company loses millions because of him, the president asks him to take responsibility by offering Hisato a job as his secretary. That will allow her to make up for her husband's mistakes, and from that point on, she thanks the president for that chance the only way she knows.
