I have a roommate whose boyfriend took the initiative to become friends with her. She and the boy are both from Xi 'an, and then once she saw the boy holding a box of cold rice noodles in his hand, and then she ran over and asked the boy which store he bought the cold rice noodles. She said the cold rice noodles smelled like his hometown. The boy naturally told her that she still didn't know after listening for a long time, and then asked the boy to add her contact information. Next time I take her shopping, I may finally meet a fellow villager, and boys will really join. Later, they chatted online and occasionally gave each other some local products. After a while, they became lovers.
