Don't say that the ultimate goal of parents is to make their children happy, as long as the children are happy and don't have a wedding. If I were you, I would refuse this request again. As a child of an ordinary family, I can ignore the eyes of relatives, friends, colleagues or others, but it is difficult for people my parents' age to do so. Not considerate of boyfriends.
Life is spent by two people. If your boyfriend really loves you and makes this request seriously, can you ask him if he can try to convince your parents? If he can do it instead of using you as a shield, you can try. He loves you and should think more about you, not just you two.
My answer is that parents are the primary factor. If I don't consider my parents, I may be able to accept it. Feel the sincerity of your boyfriend. Your love is not only spiritual, but a part of life. Such a picture is not a secular plot.
