Girlfriends and roommates always smoke in the dormitory. What should I do?

When my girlfriend finds out that he has been smoking, I will first persuade her not to be angry and slowly tell her roommate that after all, he and his roommate live in the same environment, and if the relationship is stiff, it will be very bad. So you should let your friends communicate with him well, be considerate of each other, and let them smoke on the balcony when they smoke, which will not affect everyone's life.
