You and William got married just for mutual benefit. The two sides agreed that this was a loveless marriage and lasted only 5 years. You also do not love William but only consider him as a friend even though you are married. Recently, William has been acting strangely by avoiding close contact with you. You think he's having an affair but you're not angry or upset because you don't care about it. You ask William about the woman he loves. simply because you're curious but he just keeps quiet.
