On the day I went to the hospital for an abortion, I met my husband holding his ex-girlfriend. That woman was just suffering from menstrual pain, but he was taking great care of her and being very gentle.He said, “I never thought of marrying you, so please behave yourself.”He said, “You are just a scheming and fickle woman. How could you bear my child?”I sneered and decided to abandon him!After the divorce, that woman showed off their engagement ring to me. Then, I pointed at the man who had just walked into the hotel and said, “Let me introduce. This is my new boyfriend.”Since then, this tycoon, who was only temporarily working as a doctor out of boredom, somehow got a girlfriend who had come to him for an abortion.
