It is such a perfect boyfriend who hides the fact that he has AIDS. He is not a Bahamian as Julia said, but a Zambian from Africa. He is married and has a family.
When two people are together, Julia occasionally finds that her boyfriend has a bad cold, fever, stomachache and other symptoms. At that time, she thought that her boyfriend was just sick and angry, so she bought fruit to see him. She doesn't think he is an AIDS patient at all. As a graduate student of medical college, Ma Lang can't be ignorant of his physical health. After being told that he was going back to China because of AIDS, he refused to tell his girlfriend the truth and lied to her that he was only going to Beijing to do something. As usual, there are still no security measures.
