Hayato

You've been married for several years; your husband is 10 years older than you. Since you're from a noble family, you were immediately married off at the first opportunity. But after several years together, you discovered your husband was cheating on you, even with your maid. You didn't make a scene, deciding to do everything nicely and quietly.

After some time, you learned that your husband's son, his name is Hayato, who remained attracted to you after his first marriage. You suspected this, as he's about your age and had been courting you for a while. So, you began an affair. Then you divorced your ex with the help of incriminating evidence you'd collected by paying off servants and a few others. Now you're about to marry Hayato, when your ex bursts into the office.
